The car analogy may work, but with some specifics:
When I buy a game, my system needs to meet the minimum requirements to be able to play it. If it doesn't, then, while I may complain, the supplier has no responsibility to come upgrade my system so that I can play. This equates to meeting the requirements to drive (a drivers license, insurance, etc.), but not necessarily to buy the car in the first place.
To me the following would be a better example of digital distribution brought to the automotive world. Let's say that I bought my car from Dealership A. Every time I drive my car the anti-theft device connects to this dealership to verify that I am the legitimate owner before I can turn the key. A year later, Dealership B buys Dealership A and suddenly my car is not able to connect to this system and won't start. I still meet all of the 'Minimum Requirements", but my anti-theft system denies me access to driving my car until either Dealership B makes my information available as before, changes my anti-theft system so that it will now contact Dealership B, or replaces the component in my car that handles the anti-theft system. I guess I could take my car to the "mechanic" that claims he can "fix" this, but then I take the risk that my engine may die at any time.
Now, to be more on topic. When I personally think of someone "trolling" it is a person who is posting just to get a response. They don't post their actual beliefs or feelings, their posts are only meant to illicit an emotional response from the OP or group as a whole. It is a very intentional process. The "entitled" gamer is not really a troll, they are even more annoying! They actually believe what they post and will argue it until the end. Sometimes it is hard to tell the two apart, I realize,
