I’ve just watched the video. I find it pretty outrageous. The word about it should spread.
The “purchase” agreement probably says that they can terminate the license for any reason at any time. If you bought the game years ago I suspect they are actually fine to revoke access. See for example EA and other shit game companies that have taken down games when they take the online DRM servers offline.
Yeah fun fact I actually looked this up a few days ago in the wayback machine because I own a beta account. Back then it was just Notch selling the game and the “agreement” if you can call it that on the site basically just said “you own the game forever, no drm”.
I’m not a lawyer or anything but I suspect that unless they somehow tricked users of old mojang account to agree to Microsoft TOS after the purchase of Mojang what Microsoft did may be very legally questionable. But the main issue is who is gonna sue them over 20 bucks. They know they can get away with it
