I have had some customers over here complaining about it as well, but I have never been told a reasonable explanation of why it bothers them so much.
My guess is that this concern is related to the "auto" function on the climate control, in approx 8 out of 10 vehicles I take in the shop are set to other functions than auto, I have asked customers "why?" a few times, and have been told that they think they can manage the temperature better than a machine.
The main question to me is why this feature cause so much discomfort and anger when it is so easy to switch off when not wanted?
You're missing the point. The question is why should I have to disable it manually multiple times a day...Agility Select doesn't default to "ECO" (which would save more fuel overall than the stupid auto engine shut-off feature), and almost all the other auto manufacturers allow the owner to disable the auto engine shut-off feature (like BMW).
If Mercedes was worried about their CAFE numbers, then they should have put the 9 sp transmission in the C300 as well.

BMW has the Mini Cooper to offset its fleet fuel efficiency numbers. MB has the Smart car. There are significantly more Mini Coopers sold world wide each year than Smart cars, so the regulators are more lenient with BMW. BMW is selling many more of the kind of cars that government bureaucrats want you to drive than MB is. As a result, BMW gets to offer their cars with ECO being set to default off, while MB has to offer ECO with a default setting of being on. If BMW didn't have the Mini Cooper line, then they would likely be in the same boat as MB with respect to how the ECO button operates by default. Be thankful your car still has an off button to disable this annoying and, at least in my view, useless feature. As CAFE standards increase going forward, there will come a time when we won't be able to switch this kind of stuff off. So when you start your car just push the damn ECO button off and enjoy the ride.
I am going to stand in line to say the words. It stinks.
When i tested a c450 for the first time i, well lets just say i made sure its the car i could drive instead of needing to buy a c63. After 15 minutes of above normal driving i stopped at a redlight. I could hear ticking and the car was not very calm after the treatment and the car turned off???? I swear to god i would NEVER do that to my turbocharged car if i could choose.
But. To be fair, i am sure MB has exchanged all the bearings to internally lubricated ones to handle that when the oilpressure drops in the engine so its ready when it restarts10 seconds later when its a few degrees cooler
Clogged up impeller bearings in early turbochargers were caused by poor bearings, poor cooling and a much lower quality oil. This was many years ago and the myth still lives on for some reason.
The turbochargers in M276 and M177 are way more efficient, they are water cooled and runs on high end oils.
Same goes for the engine bearings, if you know how a modern fully synthetic esther oil work there is no need for concern.

As i said, I am sure they changed all the required things needed.

Pragmatism?
I never put my climate control on auto. Just put it where you like it, and if it gets too hot or cold turn it up/down and decrease the fan intensity. Auto just sort of sends air of whatever temperature wherever it likes for however long it feels like. Doesn't really work very well.
And to weigh in on the Americans vs Europeans thing (as a Canadian, I think I qualify as an objective outside observer), Europeans should be a lot less smug about Americans than they are. You guys got a million and one problems over there on a whole host of economic and cultural issues, and while your problems are not the same ones the Americans have, they aren't any better. Now I got to get back to digging my moose out of a 10 foot snow bank so I can haul my maple syrup to market and pick up some poutine.
... there is one pattern of complaint common to several areas of dissatisfaction (including this start/stop feature). That pattern is found in the complaints of drivers who really want their car to be an extension of their own nervous system. Over 50 years ago, Road & Track and Car and Driver magazines used exactly this language to describe the pleasures of the best sports cars. In sedans, that connection is now found only in BMWs.
....
According to the review of the 2016 BMW 340i in the February issue of Car & Driver magazine that I read tonight, you can't get that connection in BMWs anymore either. And the C&D test vehicle included the $1700 Track Handling Package! Elsewhere, the Research section of the online Car & Driver says of the 3-series as a whole, "the 3-series lacks the pleasing tactility of previous generations." All things pass away.
That's a lot of hate. Have you checked out the Brabus solution for it?
I spoke with Andres at Brabus to see if they have additional systems in the works that can change defaults such as leaving it on S+, S, C, etc. but no luck... Oh and he said the ECO start/stop unit is $495 before installation. Psssh, no thanks.

Wow - bargain! You really have to hate it to splurge that much. Then again, nothing with the tag "Brabus" attached comes cheap.
You can code it with Vediamo to remember the last setting or turn it off completely in the engine ECU. The engine ECU's are protected from unauthorized code config with a seed/key challenge but there are people of course who will sell you that unlock (@$50/session).
As much as it pains some folks, the easiest and safest solution remains to just press the button
Or you pull into a parking place, the engine shuts down, you put it in park, the engine starts, and then you turn off the engine.

This happens to me every day in Australia. I dont mind the stop/start because it aids fuel efficiency (and reduces emissions), but coming to a stop after parking and the engine stops, then as you are about to release your seat belt it starts again.
Unless its detrimental to the starter motor and the replacement cost and down time of being without the vehicle impacts you more than you save over the life of the starter motor, why not use it?
Contact MidCity Engineering (search)..I bought a device from them that I plugged into canbus that automatically default disables eco every start time...can be switched back on
