Wich browser integrity? Because of Chromium? Google already tried this years ago to try to control Chromiums with infinite APIs added to the Chromium code, even with discriminatory browsersniffings, which practically all other Chromium Browsers eliminated just as quickly, Vivaldi the first. Windows on Edge anyway (naturally putting its own Spy APIs in place of these). No trackings or logging by Google in Vivaldi (as long as you do not naturally use Google as a search engine). This is why Google is now trying to gain control through its web services and pages that use them with this WEI DRM, which forces all browsers, no matter what engine, be it Chromium, Firefox Gecko or Safari WebKit, to include a "security" Google Token in your script to access these pages or services. This is naturally a huge bummer if not avoided, since then it depends only on Google which browser deserves this Token, which could be the end of all minority browsers, leaving in the end only Chrome itself with full internet access. THAT is the problem, not the browser integrity.
