A lot of MMOs also make active collaboration a complete pain, whether it's introducing a messed up matchmaking system, not dealing with bots, or adding new content that rewards you for going at it alone. A lot of content now is quite literally zero communication, not even a message in chat, just queue for group, do content and leave.
And people will spend 5+ hours a day doing that. Farming mindlessly as if it's a second job.
MMOs are that "meat". It's someplace you go for it's own sake, and (hopefully) you meet people around that shared space as a consequence rather than an intention. There will be debates, trolls and conflicts of course, but I feel that the focus on content is a shared axis that can keep things healthier on the long term.
Well MMOs are dying, and a growing number of zoomers would rather passively watch than actively play games, so I guess gamers aren't immune to social media either, but I think in the future we will return to this for answers that our present can't answer.
Social media is people being alone, together
