Forget about forking, just offering a build of Chromium for a single platform and architecture that gets the security updates in time is a lot of work.
People who remove v2, own ad networks, develop chrome and write standards are the same people. It’s new age mafia, cancer of the internet and they do everything for you to not be able to just spin off a fork.
Already done: used lying tactics to make their browser and ad networks dominate, bloated the standard to make browser development unsustainable.
Right now: rooting out the entire possibility of running full adblock-capable extensions from the sources, so that even chrome-based browsers could not support it back.
