That's... depressing but I could easily see it...
Still, I find it hard to believe that's the majority. I remember days when it wasn't as bad as it's gotten. Like is it so many people that it would truly hurt profits that much vs what it could bring (there was a point where my friends and I almost entirely stopped playing online games because these people were just making it an annoying experience instead of a fun one; I can't imagine I'm in the only group of friends that experienced that/had folks that had to take a break).
I'd really love it if someone who works for one of these bigger studios (even anonymously) said why seemingly no time is spent on really trying to just expel toxic players like would be done in real life (in the various examples you gave).
Edit: My true pipedream would be that there's some next level person (senior dev, staff software engineer, product owner) at one of these studios lurking that goes "you know what you have a point" and actually does something about this 😅
