I believe Brave and Vivaldia have announced that they will not use the Google FLoC features that Google have contributed to Chromium.
Some have raised concerns about having to maintain "their own fork" and means
extra work to synch up the main Chromium tree.
Is the reverse possible?
Can the community remove Google FLoC from Chromium itsel?
Tell Google to build it for Chrome?
Is there governance routines for it?
There’s no consensus process for including stakeholders. Forking is the only option for making changes not to Alphabet’s liking.
