Let's assume that the name and location services (or just the parts that
are subject to censorship), because they doesn't require high bandwidths,
can be located in remote jurisdictions. But your other point is still
valid. Entanglement is not really a viable defense since the censor can
always require you to remove the data regardless of whether it's
entangled. Also it's hard to see how a system that uses entanglement will
be competitive enough with systems that don't use it to attract
non-censored data, which presumably is what you'd want to entangle with.
