Don't know about some of the other titles, but Sega absolutely ruined Sonic CD classic. 1.0 shipped as a svelt ~20 MB game developed by the folks behind Sonic Mania. It was great[1]. At some point, Sega decided it needed to go free to play, so they added ads and tons of bloat to the game[2]. It now sits at ~200 MB with in app purchases to disable the ads (which don't seem to work for some people). A real shame.
However this 'End of Service' means they are stopping serving ads to the game, removing online services, and allowing them to be played offline forever.
This is a much better outcome than most games or software that is discontinued.
Indeed, but they will also stop selling or distributing them, meaning they will only be available via pirates/archivists (which are endlessly harassed by these companies).
These games will never stop being sold, they are too much of a reliable income stream. They will be discontinued in this form, and then rereleased in some new retro games pack or 'remastered' version or such like. It has happened several times before now and it will continue forever.
