Not a problem, in Vivaldi there a lot of patches against Google interests. Even Google can do nothing if the devs of other companies eliminate the tracking APIs from Chromium, precisely because it's FOSS an even Google can't revert it and can't do nothing against modified forks. There are several intends in the past, with idle tracking, FloC, and some others, also cutting of Google sync for others than Chrome, discriminative Browsersniffing in some websites to block Vivaldi and others. Nothing of this worked. Vivaldi is a small european cooperative with few devs, but which are among the bests out there. Now on top of that they have managed to introduce Vivaldi into the world of Browsers and its use in Mercedes, Renault and VAG, that has not even been achieved by Google and with this also eliminated the possibility of acting against Vivaldi, without messing with these Companies. This is showing a really big middle finger.
