Windows 11 is horrendous but so is this article. I've installed Windows 11 on probably 10 machines and I've never seen 'TikTok' preinstalled but assuming that it can be in certain regions it really isn't that difficult to remove the default bloatware apps. As for the rest of the problems this guy mentions, has he ever heard of Group Policy? Even if you're on a version that doesn't have access to GPEdit, what about the Registry?

Windows 11 has a fuckload of problems and is objectively a step or 12 backwards in terms of configurability, but this article doesn't really sell the problems very well IMO.
