A Sybil attack seems like the most likely weakness then.

Why do we trust permissioned nodes to not get compromised or the permissioning body to not accidentally or intentionally let in malicious nodes?

Couldn't a few well placed gag orders by a sufficiently powerful government be enough to subvert the whole system in a non evident way?

It could, and that's why a solid threshold network should have nodes in different locations, jurisdictions, cloud providers, etc. and have a threshold that's high enough to avoid that risk.
