I know this is going to sound "bad", but unless you bought the game and now it stopped working, you don't have to be complaining so much, you didn't get ripped off, you didn't lose money, etc.
and before someone comes up with something else, I'm not saying that pirates can't complain or give their opinions but come on they haven't lost anything to start crying complaining and accusing dev of certain things (for someone "greedy" they did change the engine very fast, other people would stay more months giving us the same content or restarting the development).
those people should just look for games that do support their old pc, and definitely think about upgrading their components.
