Issues include damage to paint during removal, the film coming off in pieces, and old adhesive not coming off. In the worst cases, the paint comes off with it... especially the low VOC water-based paints they use nowadays. The irony is that the worst problems occur with urethane bumpers - precisely the areas you are most likely to protect. 3M PPFs are especially bad because the adhesive is super-strong. Cleartastic seems to be less problematic to remove. The older the PPF, the worse the problems. And it's not just the PPF and the adhesive... modern auto paints continue to evolve chemically as they age, and the process of deterioration is worsened by trapping them under a non-breathing layer (remember how the old bras damaged paint?). Same deal here, and the clearcoats are especially susceptible.
So, stay away. Personally, after what happened to those guys, I won't even touch a used car that has it. If you have to coat, then use ceramics. The only exception might be an area on a car that you know is going to get beat up either way, such as lower rocker panels, rocker extensions, low vents and ducts etc. An example is the C7 Z06/GS. Every Z06's rear brake ducts get trashed because the sticky tires throw up a lot of junk and the front tires are fully exposed at the rear of the front fender. So you may as well PPF because the ducts are going to get trashed anyway. Ironically, this area is really tough to do with PPF because of the sharp angles. So in the one case where PPF might make sense, you can't really use it!

MY 2c: no issues and no damage following manufacturers suggestion: Using the hair dryer TO WARM UP SECTIONS AND EASY PULL OF THE PPF.

If no PPF is on it, you'll eventually look at a respray unless you like looking at sandblasted paint. Ceramic coating does nothing to protect the paint from chips. It just makes it easier to clean due to the hydrophobic properties. I guess it comes down to what you prefer. A sandblasted, rock chipped front of the car, or potentially some paint damage if the film needs to be removed for some reason.
I've yet to have a reason to remove the PPF in the first place and I keep cars for 6+ years typically. Actually on second thought that's not true. I had to replace the film on the rear bumper of my previous car after 6 years, because somebody in a parking lot bumped into me. No paint damage. They just replaced the film. Earlier films used to yellow, but again environmental conditions always play a role. How much UV exposure did the car have? Was it garaged? Was it driven in harsh winter conditions? Cars are meant to be driven and that means they'll sustain damage sooner or later, one way or the other, but PPF keeps it looking great until then. Life's too short. Can't take that Ferrari with you to the grave.
