I'm also in the "I don't care" camp.

A lot of us just want a piece of nostalgia that the big companies choose not to produce.

If it looks close enough that it inspires my happy nostalgia, and it plays fine in my console, that's what I'm happy to pay for.

If the license holders are still selling the game, I'm happy to buy from them. If not, I'm happy to buy from someone else producing reasonable facsimilies (of abandonware games).

I get how someone could be upset if they thought they were getting the real thing.

I haven't, personally, felt misled by makers of abandonware facimilies.
