Also, it would be helpful to actually understand what kind of metadata is this referring to and specifically in which cases does this apply and which cases are exempt… because I expect that if the design of a service explicitly makes it so all the metadata you can collect is not helpful/reliable, then you wouldn’t be forced to redesign the service, you’ll just provide metadata that’s unreliable.
I feel these kind of measures never are really effective at stopping organized criminal activity (since those looking for a way will find it), what they are effective at is tracing/tracking non-criminal private use.
Pretty Good Privacy (PGP): The first implementation of a set of methods used for signing, encrypting, and decrypting texts, emails and files that ultimately became a standard called “OpenPGP” (RFC 4880), the program itself was commercial/proprietary. Sometimes “PGP” is also used to call the standard itself for short.
