Mind reading Necromancers (probably) don't exist, but every example I listed above has already been deployed in a piecemeal manner in various countries the last 10 years.
Mass File Sharing Blacklisting has been enforced by Indian ISPs since 2019
VPN+ISP traffic log sharing has been enforced in Kazakhstan (along with SSL stripping)
Blocking Tor downloads has been implemented already (with varying levels of success) plus attacks to deanonomize Tor have started occurring since 2021.
App Store restrictions and region locks have existed in Mainland China since the early 2010s.
It's very easy to tamp down and censor internet based communications. Individual corporations have the capabilities to apply such censorship if they wanted to, let alone ISPs.
