Anecdotal experience: I switched browsers on android because android's default browser kept opening map links in google map. Firefox mobile didn't seem to suffer from that issue.
While google's tight integration lead to a positive experience for you, it lead to a very poor experience for myself or others who want to use something not google. I'm not asking for the EUC to fine google, I'm asking for choice.
Not 100% but I thought that android asks you the first time you click on a maps/wiki etc link would you rather use browser or app and whether you want to do it once or always.
I agree with you that choice is good. That is kinda why I proposed my very simplistic solution of Google offering two ways of searching. One stream which tightly integrates with the Google Ecosystem which would be a plus for many people (like myself) and another where they just give you the results without any integration.
Additional bonus, Firefox Android has extensions, so you can get uBlock Origin and such :)
I have a similar problem with Google Maps. I don't want it tracking my location history to my Google Account (integration I never asked for), but when I disable this it even refuses to remember my search history for addresses and such (no reason that needs cloud storage except Google wanting to get their hands on this info). Therefore I most often use Open Streetmaps with Maps.me. Which has other advantages too, so it's not all bad.
