It is very likely to be a censorship order. There's this supreme court judge who wants his personal enemies suppressed and he's gonna make it everybody's problem until he gets impeached. I've read documents where he calls technology like VPNs "subterfuge" and threatens totally arbitrary fines to anyone using such things and any such service making itself available to brazilians.

Proton made its VPNs freely available in Venezuela after the fraudulent elections. They're probably aware of it. These people are all defenders of the venezuelan dictatorship after all.
