Google has never tried to sell my data or show it to third-parties, though.
But you have no reason to believe they won't in the future. Honestly, thank goodness for Mozilla and I hope they can keep up with browsers for a long time because the web will be a horrible place without Firefox.
Why would Safari (which, although not perfect, is in fact available on Windows) + pure open source Chromium (Chrome without Google stuff) not be enough of an alternative?

This applies to everyone, including Mozilla.
Because it's easy to verify that that isn't the case. If you don't trust the Chrome binaries, feel free to use Chromium (which is of course completely open source). Further, I'm not sure what the actual implication is here (Google is reading your HTTP traffic?), but it would be easily (dis)proven with Wireshark and would be an enormous scandal.
