I like Google search as well, and I'll look at a bunch of ads on it if I have to, but I don't see the logical connection here how that implies we need to tolerate bad standards in web browsers or the android platform. Spin-off ads and search from android and chrome and search will be just as great and we don't need to infest web standards with rules that only exist to serve the ad business.
I don't practise any double standard here either. Same goes for apple. If they use their app store to stop competition by for example Spotify to promote apple music, break that up as well. The same thing for amazon, if they use AWS money to price dump on eCommerce or disadvantage third-party sellers, break it up.
I don't have any favourites here, whenever one of these companies engages in activity that is clearly bad for the ecosystem just for their own benefit I would like to see a very rapid and proactive response.
