@404mediaco It's not ProtonMail's fault; they have to follow the law.
If they just handed data over without being legally required to, that would be concerning, but that doesn't seem to be the case here.
@iampytest1 @404mediaco it's was Proton's decision to move to USA jurisdiction, not?
@egonw ProtonMail isn't based out of the US. The government of the country it is based out of demanded this information, and provided it to the FBI under a MLAT.
