It depends, but I agree that this is a crazy hard problem to address correctly
and not create dystopian side effects or even just risk that.
Imagine you need some QoS on a few streams for serious and useful purposes (telesurgery comes to mind). Core networks are able to provide that, but this is not usually mapped to user extensible protocols on general purpose/public access points.
Now there are indirect advantages in just not providing those, because:
- you also reduce the risk of dystopian usage / restriction of usage / etc.
- in some cases, you make mass-applications being developed for non-QoS networks instead, so you eventually end-up (maybe a few years behind, but this is a cost I'm willing to pay) with basically the same service on a simpler and less dependent to political context tech.
But:
- in the context of a benevolent legislation, this could be actually more useful and fair than the current situation, where network neutrality has became half a myth both in theory and in practice (there is no practical neutrality anymore when you can just put your own private datacenters all over the world plus high bandwidth links to supposed neutral providers, then use that to push your proprietary services/applications without emerging/low capital competition able to do the same)
- so you actually depend on private parties to be benevolent with the supposedly "best effort" but actually not anymore approach
- and then it is a matter of taste, but in some part of the world I'm more inclined to trust elected politics (even if they sometimes do some bullshit) defining regulation than private soulless multinationals with the often stated theory that they must optimize shareholder outcome and nothing else.
That being said, given both the current state of the world (and even if it was better, the always persistant risk of it degrading) and the practical difficulty to cleverly and benevolently regulate fast moving technical fields, I'm willing to stick to basically the current situation, which seems less prone to extreme situation.
But it would be a mistake to view authenticated QoS as inevitably and purely evil.
