I thought the Windows "here, let me do something for you that you explicitly didn't want me to do, and oh BTW xbox controllers are on sale" thing was an exaggeration, but no!
The Windows 10 PC I keep exclusively for customer support just actually and literally advertised Xbox controllers on sale to me, unprompted, on startup, from the built-in unlisted app "Suggested."
@earthshine True, but I sleep better at night when the problems I fix are hardware fault replacements and software fault corrections, not "my own computer encouraged some random scammer I can't touch take me to the cleaners."
