It kinda gets different when you’re talking about a series of actors intermingling in an environment designed by the seller.

I think that gets problematic. We are very often “intermingling in an environment designed by the seller” for agood reason, which should not be denied. Let’s have a look at websites: changing the style, tracker and adblocking (or even just blocking all the scripts), … I want to be able to do the same with any other program I run, like I take steps on my Android phone to thwart apps tracking me when I can’t find a better, open source alternative, but if a judge would use your argument, they would probably say that even using firewall software to deny network connections to the program is unlawful.

I don’t agree with cheaters using aimbots, wallhacks and whatnot, but it’s because it directly destroys the experience of other players.
