This kills me. I uninstalled Apple maps and I have to manually copy locations into Google Maps from the mail app. Clicking location links prompts me to reinstall Apple Maps. Obviously a very intentional decision.
When I go to google.com with a browser other than Chrome, I see a pop-up "Switch to Chrome, a smarter browser. Google recommends using Chrome. Try it? [Yes]" Each company leverages what they have to try to push you further into their ecosystem (or as Bruce Schneier would say, further indentured to that feudal lord).
