Re: the least evil biggest game companies, isn’t Valve pretty OK? I mean considering they have a staggering monopoly* on computer game distribution they’re in a position to be pretty evil, and often are not as far as I can tell (unsure of human rights atrocities on their résumé which was the focus of the question)
*not using the term quite correctly—obviously there’s GOG and Epic and itch etc, Steam isn’t the only game in town, but it feels like it is!
