Apple, Proton and Wire helped Spanish police identify activist

I am not doing anything remotely controversial or illegal but I sometimes wonder what's the best provider if you are somehow "at odds with Western powers".

In this case it was probably opsec failure with the recovery address but I am wondering if Proton mail is any good if they bend to any law enforcement request.

My gut feeling says you might be safer with some Russian or Chinese email provider. Obviously this has risks on its own and I am not keen to associate with these countries, but for someone like Catalan separatist it might work better?

Are there better providers? Running your own email on some very shady server provider? Relaying emails somehow?
