Google is the master of this. Every piece of software they have keeps logs of everything you do, every key you type and every button you push and what devices you're connecting from and who you talk to and where you are and what you're doing at all times. Neither Microsoft nor Google can be trusted in that department.

The only company that tries at all to respect your privacy is Apple. Google has a photo album with facial recognition and automatic tagging and the ability to search based on what the subject of the picture is, but it requires that you upload all your pictures to their servers so they can search through them. Apple does the same thing but the pictures never leave your device.

You'd never expect to see Microsoft or Google get up on stage and say "we're intentionally giving up an entire revenue stream because we respect your privacy". Instead they subsidize the cost of their software with privacy invasion and then brag about how much better value for the money their products are.
