I think your example wins, OP, but I will say for anyone who works in an office environment: Microsoft Office (or Libre alternatives for my FOSS friends which don’t have logins to begin with but whatever).
Imagine if you had to log in every time you opened up a document, and you get automatically logged out after 10 minutes of inactivity and lose any unsaved progress.
Global productivity would grind to a halt. (That, or people finally switch to LibreOffice or similar, but corpos will still reliably do whatever decision seems dumbest).
I have to imagine competing with a de-Googled Chrome is also a concern. I wouldn’t think this apples to the majority of users, but a lot of people currently using Firefox today are only doing so because of a dislike of Google (and Microsoft), who might be willing to go back to a responsibly managed/truly FOSS Chrome.
