When people leave Google Search (and they will, nothing lasts forever), they'll leave fast.
Further, because of mobile, there are significantly greater number of Google users than there are Windows users.
I guess I am annoyed because as someone who uses Firefox as their primary browser, it always frustrated me that there was t more outrage at Google pushing people away from Firefox. But the moment MS started doing it, it became an outrage.
Accounts would be the hard part because that's my phone login, and there's no standard account service I could migrate to that would give me a functional replacement.
The real thing keeping me on the Google platform is the convenience of having these things tied together. But that's not exactly a strong lock for me. I can and do hop services while sacrificing convenience. This might be a stronger hold on others but it's still not Microsoft's you-can't-do-work-in-any-organization level of hold between Office, Windows, Exchange, etc..
* This has actually been annoying for me lately. The results favor the things I've already clicked on which is often exactly not what I'm after.
