Semantics aside, there's an objective list of who bans or censors more, and it's not even close. Not by an order of magnitude. Source: the great firewall's existence.
This is interesting. I agree, to some extent, but there's nuance in what do you include in the objectification of the concept. The usual argument, as I perceive it, is that we can be objective if we just quantify protocol interference, or DPI, or bogus DNS resolution.
But still, not all blocks are born equal. That's a bit of beating around the bush to avoid going one level up in the abstraction of information controls. There's a thin line between content moderation at the platform level and mandatory hijacking of the DNS system via legal means.
If you squint, they are just a different configuration in the phase space of distributed technical systems, corporations operating in nation-states, and national laws.
