I use the the ‘right click button’ literally every single day. It’s super useful for not having to move between the mouse and keyboard for tasks.

Also, this is on Linux, and I think it’s fair to say that the key has evolved to become a fairly standard part of keyboards and operating systems. Just because MS were the first ones to use it doesn’t give them some kind of say control over the idea, at least beyond the scope of their own hardware, and I don’t think anyone is arguing that they don’t have the right to change their own hardware. It’s just a bad decision.
