I doubt they do mich different than you do with their OS.
People are more motivated by feelings than actual logic. The person you are responding to even states that Ubuntu “feels good to use”. That is some car advertisement level of feeling based reasoning.
Another thing is that people really hate it when things change. Especially a UI change. Every change in the Windows UI has been met with disgust. And if there is one thing different between linux distros, it’s where they place all the buttons, menus, etc. So people prefer to stay with the distro they know.
Before Microsoft demanded TPM 2.0, you could install the latest version of Windows on extremely old hardware. Easily reaching that 15 years. We had this already. And Windows 11 can easily run without TPM 2.0. Microsoft just has business reasons to demand it. So I don’t see how innovation is slowed down by this.
