IE like Crypto AG:
In 2020, it was revealed that the Swiss company, Crypto AG, which provided secure communications services to ~120 governments throughout the 20th century, was secretly ran by the CIA and West German Intelligence. The CIA and later NSA were able to read encrypted communications for many countries such as Saudi Arabia, Iran, Italy, Indonesia, Iraq, Libya, Jordan and South Korea.
So you have two different countries, two different sets of laws, and two different services with wildly different offerings.
You can’t really compare a drilled down percentage of compliance and reach the conclusion that there’s a difference in methodology under those conditions.
Just the much broader spectrum of services that proton offers makes it more likely that they will be in a position where they are required to comply with a larger portion of requests than tuta.
This is not intended to be a defense of proton, just a recognition that metrics are hard to take seriously in a comparison.
