Firefox have the same problem with the WEI filter, they also have to insert in Firefox the Google Token, same as any other, if he want to enter a Web with this fucking filter, anyway Mozilla will do this in FF precisely because several Google devs in Mozilla which are working on FF (Bad decision of Mozilla to have Google as main sponsor). Ad/trackerblocker are not the problem in Vivaldi, it has inbuild the needed filters (even those to block Cookie advices and adblocker warnings) and until now it has gutt out every Google intent with FloC, IdleAPI and others to control the Chromium base (remember, also Chromium is FOSS and customizable,above with first class devs Vivaldi has), also don't have and don't depends on extern inversors, but this fucking WEI DRM of websites is a greater problem and need to be avoided by ALL browser companies which are not Google in common, if there is not a genius which invent something to fake this Google Token. We'll see.
