MS may have reason to be nervous.
Just as users put their livelihoods on the chopping block storing their data on other peoples' clouds and subscribing to web-based software, the features of which, or their access to, can be pulled at the drop of a hat, MS is placing itself at the mercy of a third party with OpenAI. It may have been wiser to configure AI better as something that could be turned on or off by users, and could use multiple vendors' processing. But they didn't. And they may no longer be able to roll back.
