Microsoft has done a lot of super shady things, and they are domiciled in a hyper-corrupt, lawless threat to humanity (one that elects quite possibly the stupidest human alive -- a rapist abomination halfwit clown -- to the highest office), however people do make far too much of the patent thing.
A lot of firms reward groups and employees that get granted patents. It doesn't actually matter if you're spitballing the most absurd nonsense that no one ever asked for and is nowhere on the product map, someone writes the application and gives it a shot. A patent being granted doesn't mean that a single person ever envisions doing this or asked for it implemented, and honestly the idea that they "invented" this is just how farcical the patent system is.
In this case the patent is held by Microsoft's "Microsoft Technology Licensing LLC", which is their "patent extortion" racket. So they literally wrote this hoping to catch someone doing something found in a single claim so that they can use the legal system to rob from people.
