For the last few years, most MMOs have been, or become, Free to Play, with (a lot of) microtransactions. The only subscription MMOs I can think of off the top of my head are FFXIV, WoW and Eve. Then you have the buy to play, with no sub (or optional sub, but not required to play), games like New World and Elder Scrolls Online. Making the vast majority F2P.
All of those games can become EOL and be removed from sale for any number of reasons, and they’ll have the same terms in the EULA that the crew would have. There is literally nothing different legally between The Crew and something like Elyon. Both were paid for up front, no subscription with some optional microtransactions.
Since legallly there is nothing different between all these live service games, it makes this youtubers campaign all the more odd. Car Licensing is notoriously well enforced, so why is this guy, a Half Life youtuber of all things, thinking he can go after Ubisoft on this when it’s pretty obvious that it’s the license agreements that are the likely cause of the shutdown.
The reason you can still play UT99 and 2004 is because those games were never hosted by epic on a central server. The game shipped with the server hosting tools, and it was designed to allow you to host your own server (if your connection was fast enough) or to rent your own server from a third party.
They’re also very different types of games from the current crop of live service games that this youtuber is targeting.
