Would you prefer an OS that lets Microsoft spy on you, or an OS that lets the entire world spy on you?
Obviously the correct answer is "neither," but if you're deciding between Windows 7 or 11, that isn't an option you seem to be considering. Random people on the internet in countries with lower costs of living than yours will happily install malware on your computer to drain your bank account or cryptolocker you for a couple thousand bucks. Microsoft makes way more money than that (as does every single Microsoft engineer) and doesn't care about attacking you, at least not in that way.
(Also keep in mind that Microsoft surely has a bug tracker with a pile of WONTFIX'd security vulnerabilities in Windows 7 that they just didn't get around to fixing before EOL, and almost certainly that bug tracker is less locked down internally than raw telemetry data, so if you assume Microsoft or its engineers do care about attacking you, that's probably easier on Windows 7.)
