Doesn't Minecraft have its own controversies with Microsoft imposing various forms of direct control over ostensibly private servers? Anyway it's obviously a special case regardless because of the unusually expansive modding community. It's hypothetically possible for games to have a private server friendly business model, but the trend has been for the biggest successes to have a freemium business model which arguably would make less money if they offered private servers (because people would use them as a way to avoid the exploitative bullshit the game is trying to profit from).

Not to say that such a requirement would be bad for videogames. It's just clearly a much bigger fight if companies have reason to believe a law is a potential financial threat to them, and they would have much more reason to think that with a private server requirement that isn't limited to EOL games.
