I don’t know much about the case beyond some very lazy peripheral searching, but it strikes me that Proton’s compliance isn’t an issue, but the requests themselves are totally unjustifiable and based on malicious prosecutions to nab some separatists on ridiculous terrorism charges for their nonviolent action and protests.
This individual is suspected of being a member of the Mossos d’Esquadra (Catalonia’s police force) and of using their internal knowledge to assist the Democratic Tsunami movement.
The requests were made under the guise of anti-terrorism laws, despite the primary activities of the Democratic Tsunami involving protests and roadblocks, which raises questions about the proportionality and justification of such measures.
