Google Chrome is now encouraging uBlock Origin users who have updated to the latest version to switch to other ad blockers before Manifest v2 extensions are disabled.
Don't think Google would be at fault there, at most it would be the fault of the website that served you the ad or the service that website used to serve you the ad. (Which could be Google but they wouldn't be at fault for not letting you block ads, they would be at fault for serving you a malicious ad)
Luckily the one webapp that I have to use chrome for doesn't even have ads or tracking on it. I use Firefox for everything else, so uBlock will continue working fine for me.
