This isn't a Microsoft thing, it's a big dumb corporation thing. Most big corporations are run by dumb executives who are 100% out of touch with the customer (though even if they were in touch, they wouldn't care). Their only consideration is the stock price. If adding new names to things, chanting the magic spell "AI" over and over, and claiming the new name will make them more money can cause the stock price to increase, that's what they'll do. (Making customers happy doesn't make the stock price rise; if it did, we'd all be a lot less depressed and a lot richer)
