For number 2, the EU's new regulations above more easily replacable batteries, mandatory USB-C ports and such, in my eyes prove -- though not doubtlessly -- that they do care about walled gardens in tech.
Number 3 though, again, as I've alluded to before, doubtful. But possible in my eyes. Urgency is another thing you've mentioned, and -- let's say it again -- bureaucrats are not particularly known for solving a problem in the right time.
NB: don't misenterpret my use of 'bureaucrat[ic]' as a negative comment, it is just a fact, however boring.
