Because clickbait headlines are surprisingly effective.

Because they shouldn’t be doing this at all. The versions of the apps in question, and even which specific apps, are complete irrelevant.

Because I haven’t yet updated from Windows 10 to 11 and had been putting it off. In the past week, though, I have seen a number of news articles highlighting issues I am going to have with Windows 11 and this particular article, indicating that they have been effectively leaving systems vulnerable simply because they have applications they don’t like installed is just not good enough. I’d understand it if they were saying “we can’t guarantee your OS stability with these apps” or “we can’t guarantee these apps will work anymore” if they were removing older API support, but this is ridiculous.
