Just Hi-rez being Hi-rez. They have a long history of shutting down games. I’m never getting any game from them anymore.

I don’t think it’s the same source code (uBOL vs uBO). And it’s definitely not the same logic, that’s the whole point, blocking with MV3 must be done in a declarative way.

They do kill uBlock Origin. The Lite version is a different extension.

Yes but that’s not the same. Because of Chrome limitation it can’t update it’s blocklist directly. You have to update the whole extension to update the blocklist and that goes through Google validation in the Chrome store. It adds delay and Google could even refuse some updates. The blocklist is also shorter because not all filter rules are supported.
