Possibly the liberties they take in presuming to know better than you?

Maybe, but I do sometimes appreciate introductions to new features when they're significantly different or improved. From the user's perspective I wouldn't consider Edge to fall into that category. Sure under the covers it's radically different but functionally not so much.

I think were the guided tours really annoy me is when they know who I am but insist on showing them to me across all my devices with no escape.

I actually got this update a few weeks ago on one of my machines and immediately rattled off bug reports to MS about the fullscreen BS and the importing of FF history. When I received the update on another machine a few days ago, the importing didn't occur. I assumed this was MS correcting an err in judgement but based on the reports that's not the case.

The just don't appear to be doing the import step to the same account twice across machines, that's nice I guess... but it's like not having diarrhea gravy poured on the second serving of shit sandwich you're being fed nice.

Lack of user input. Extrapolating MS could introduce "new" Edge every week forcing repeating the whole process on 1 billion people.
