Switzerland never had solid privacy laws - and is known for intelligence service overreach for decades.
They had a Stasi like system of "who to imprison" when "the time comes".
They listen to all IP traffic in and out the country - which is concerning in times of traffic pattern analysis. And they are known for their close cooperation with US intelligence services.
Protons (and Threemas) claim of "soo good swiss privacy laws" is nothing more than swiss-washing. And they know it.
Proton has already given away data of its customers (climate activists) to the swiss authorities. And only talked about it when the press got onto it.
