looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )

Stop using Google products I don’t know how else to fucking say it.
Chrome -> Firefox Drive -> sync or Dropbox or any number of options Sheets and productivity tools > libre office or Apache open office YouTube -> Invidious or even better, odysse Google search -> duck duck go, SearXNG, StartPage, etc Gmail -> not a ton of great options. I’d probably recommend proton mail but the FOSS email world is definitely lacking, or gets blocked or goes down, harder to self host etc.

Brave has done too many shady bullshit things and has thus completely lost my support and interest. I do not recommend them.
