Microsoft and Google show you ads regardless of if you pay or not.
Seriously even my alarm clock app that I pay a monthly fee for tried to ask nicely if it was ok that they tracked me across web sites after Apple started enforcing their new rules.

And: If anyone has a good alarm clock app for iPhone that makes sure I'm out of bed before it turns off, and that is a one time payment or a reasonable fee or even open source I'm all ears.
You're doing that either way, just like you're going to see ads regardless of whether you paid $$$ for a Windows license, pirated a key or just life with the water-mark and other limits of an unlicensed Windows.
