Not really. Take Minecraft for example – before the acquisition by Microsoft, servers were entirely run by individuals/groups who set their own moderation policies. Some servers were entirely PG-rated, some allowed cursing/sex stuff/etc. Mojang technically still had some level of control over things like skins (which were centrally managed), but otherwise it was choose-your-own-moderation for each individual server.
However recently (and widely discussed on HN[1]) Microsoft has started censoring the entire ecosystem, to the point where you can get banned from all servers for chat behavior in one server, because your MC account is now your MSFT account. So they can just ban the latter to block you from all of MC (except for cracked servers).
