The point isn’t to block Proton as much as give prosecutors and investigators another tool to either target folks or simplify prosecution. If a search reveals a Proton email address (or you can show someone using one), you’re done.
> so far as I can tell, using protonmail isn't illegal yet?
Not an expert on Indian law. But we have a court order blocking Proton Mail across India. Circumventing the block could be found tantamount to wilfully violating the court order.
no, i dont think that's how it works. if someone is using protonmail they won't be violating court's order. the order is just for protonmail to be blocked. doesn't say anything about the people using it.
