I tend to use duckduckgo for search and use fedi for social network so very few ads, we have windows 10 at the library I tried to look for an image to use for a project on openclipart.org and the site is totally borked due to ads, which I don't get here at home.
Visited PC world / currys the other day, Windows 11 seems to have some side bar thingy with ads, news links and other garbage, no idea what that is for, so that is enough to put me off windows 11 for a start.
Thank fully Debian has better support for non-free hardware, so any new PC will have the Windows malware removed in full and replaced with a proper Operating system as in GNU / Linux at the core.
