By now you know that Microsoft is now defaulting to saving new Word documents directly to OneDrive. I guess Excel will be the next inline. The cynical take is that this is incredibly convenient for them, especially if they plan on using that data to train future LLMs. Imagine paying for software only to have your data automatically funneled into their cloud. Plus, what happens when you're offline and need those files? Just use the LibreOffice and just say no to all Microsoft products.
