Most Chromium-forks are not interested at all (or do not have the resources, considering the tons of costs it has) into doing any core changes to fight against Google, only Vivaldi… all the others are either doing nothing or just PR bullshit.

If a feature is rolled out to 95% of users, then websites have to adapt. If you have a browser and are part of these remaining 5% you will be the one blamed by the users and by the websites. So there is no incentive to remove any hostile feature.
