I don't want this feature. I have LaTeX documents on my computer containing my personal thoughts. Some of them I want to keep to myself. And some of them contain my own ideas that I find embarrassing. I don't want to hand those documents over to Microsoft servers, nor do I want them used for AI training. I want them to know that these deeply personal thoughts are mine.
At this point I would ALWAYS assume that anything I do on a Windows system is not completely private, and the only true way to make a PC secure from Microsoft is to air-gap it.
Also, this is completely ridiculous.
