There’s a reason the word “multifaceted” gets applied to people sometimes. There are different faces we present in different scenarios.
Sometimes people will be one way with family, another at work and another way again when with friends. There are funny stories (or webcomics) of people ending up in a group that comprises a family member and two people they know from respective second and third groups and the humour is that they have no idea how to act in a way that won’t confuse at least one of the people they’re with, including themselves.
As for relating to your situation, there was one online content creator who went by a name that sounded like it was based on a real, given name and not something made up. It was a bit of a surprise when I learned that wasn’t anything to do with their actual name. They also posted things that were out of the mould I’d mentally put them in on another social media site.
(Being vague because I don’t want to dox or disparage.)
Thankfully, those particular revelations affected no-one but me, which might be a way for you to look at the situation with the person you’re talking about.
Maximise profits and minimise losses. My guess is that someone important at Microsoft thinks that this will do just that, and if not that, will make them, personally, a lot of money. That person has no-one who will dare challenge their authority and so we go down this road.
They (that individual or Microsoft as a whole) almost certainly have a stake in the companies that provide newer hardware, and if they didn’t before this decision, they will have by now.
It theoretically makes Micosoft’s job easier too. A huge chunk of backwards compatibility maintenance goes out of the window, if you’ll pardon the pun.
“Oh you have 5 year old hardware? We don’t support that.”
Sounds fairly similar to Apple’s business model if you think about it that way.
