The headline is a bit overdramatic. Google hasn’t pulled uBlock Origin off its extension webstore. Rather, it’s switching from Manifest v2 to Manifest v3, which won’t support features the current version of uBlock Origin needs to work. We’ve known this was in the process of happening for months. It’s a good reminder of what’s coming eventually (namely, the fact v2 extensions will be entirely disabled by Chrome soon), but this is nothing new.
