It's hard to put a number on shittiness, not sure how to objectively look at this at all so idk what to say besides that this seems very much out there to me. They don't have any illegal monopolies (acquired not through being better but through a legit monopoly boosting their other products), don't run the biggest tracking ad firm in the world, don't track you across the web after luring you into logging in in the browser, don't have a closed source version of the browser with more features, don't deprecate functional ad blocking, don't run walled gardens like youtube... it's hard to come up with a single way in which Google is more trustworthy than Mozilla. How can you say they're even close to up to the same shit?
