Even if you only read the headline, you can work out the most likely story from logic. Someone else in this thread already said it: they're not gonna go to jail for you over a small subscription fee, of course they're complying with local laws and then the Swiss people handed it over to where they got the legal assistance request from. It's also not the first time Proton cooperated with a legal request from Swiss authorities, or Signal or other similar companies for that matter. The story tells itself no matter what part of it they decide to stick in the headline
Nothing of that email is new to me, and I didn't read the login-walled part which was like the third paragraph onward or something (I think it said it's free to read once you sign up, so not a paywall, but yeah either way)
I think 404 Media has an ethical obligation to provide Proton Mail’s response outside the article’s paywall. The word “Helped” in the headline is more sensational than stating that Proton “was required by Swiss law to provide...”
For readers who do not want to pay to read the article, the headline leaves incomplete context and creates a misleading impression of the story. That damages Proton’s reputation, and the missing context is only available if someone pays for the article, reaches out to Proton, or searches forums for substantive information.
