When I was quitting some vices, just interrupting the automatic Bored->browsing transition was enough to get me to make other choices
I only access HN from my mobile now, which I put out of reach when working.
It depends on what you mean. Do you mean some sort of mechanism on the ISP's account page that lets you delay certain sites? IMO that sort of functionality would be better self-hosted, though I'm not sure of any open-source projects offering such functionality at this time.
If you are proposing a mechanism where the user does not have control, no it would not. The whole point of net neutrality is to not slow down certain sites. Even though Ajit Paid fucked that up, I imagine people would not be very happy if an ISP slowed down certain popular websites. I imagine said popular websites would be used to speak out against this too, paradoxically.
I configured screen time in iOS, but it just don't work, I know the code.
I can confirm that screen time doesn’t really work unless a different person controls the code.
But I can understand why. This could be a recipe to break a device.
