Plugged laptop into my USB-C dock as I often do, but the two external screens were mirrored. I tried everything - replugging, rebooting, downgrading the kernel. The OS was only seeing one screen. Tried replugging everything into the dock. Finally I unplugged absolutely everything, even from the wall, replugged it and it worked perfectly. So I conclude it was electrical interference. Now I'm not so sure about USB-C "power going both ways".

The connector itself is fantastic, but trying to use one connector for every possible voltage and bidirectional charging does complicate things. However if it works it greatly simplifies things for the user.

Oh... I thought you have blocked me months ago 
I just hate the idea based on how inflexible the law tends to be. If a better cable got announced tomorrow, we will have to wait another decade before EU will get to changing the law again to allow it.
True, but I do like that the EU made Apple cut its bullshit, even if it sets a bad precedent.
@alex
Well, we'll definitely disagree here.
Apple sheep might have a better life now, but I have lost yet again a small peace of freedom because of a problem, that didn't affect me in the slightest.
@alex
Also, I would add, do you remember mini USB? That cable appeared and got discontinued almost instantly.
That is the freedom, that this kind of law would not allow to repeat. Nah, I want the best, no matter if the law makers are ready.
