It is really crazy that we are taken hostage/blackmail by whatever harmful decision Google takes in their own interest.
Chromium is open source, you're free to use it.
This is irrelevant because the changes are occurring upstream in Chromium by mostly Google developers.
Open source also means you're free to fork it or freeze your version
Forking is untenable for individual humans with something so complicated, and freezing is dangerously insecure.
