A) I'm not going to watch the video because it's hosted by goggle, and I'm not interested in being goggled.

B) However, even without watching the video, it must be describing corporate product UI, because in the free software world, there is a huge variety of selections for desktop (and phone) UI choices.

C) The big question I continue to come back to in HN comments: why does any technically astute person continue to run these monopolistic, and therefore beige, boring, bland, corporate UIs?

You can have free software with free choice, or you can have whatever goggle tells you...
