I think this whole conversation is mixing two types of disagreements and is going to end poorly for that reason.
Absolutely! People who support it because of philosophical reasons are getting very upset over people giving practical criticism. Portability and maintainability of software are complex issues people make entire careers out of solving. You can't just make it illegal for software to stop working.
That doesn't mean companies should be allowed to purposefully brick your games for no reason, but there are cases where ensuring a game works forever would be a huge burden. The petition offers no exceptions, no practical guidelines, and no suggested punishment. It's just "If you sell a game, that game must work forever, or else". I see that affecting more small indie devs than large greedy corporations.
