I have. It's bad.

Pavlov (one of the other comments) has it right with the Overton window comment:

- Compared to ChromeOS or Android, Windows 11 is the ultimate in privacy.

- Compared to Google Docs, Office 365 is the ultimate in privacy

... and so on.

With Google's or Meta's surveillance infrastructure, if we get a Putin, Hitler, Stalin, Mao, or similar (and I'm by no means trying to equate those individuals), individuals who checked their data in will be !@#$%ed.

On the other hand, I don't feel like people are putting themselves in danger using Windows 11.

Personally, I use Ubuntu + emacs + libreoffice.
