dlb It doesn't matter. They gave up customer data. What is the point of having VPN then if they sell your data.
Proton didn't sell anyone's data, nor was this case related to their VPN service to begin with. You are letting the facts get away from you.
Graphite chuck if the user used vpn
I think you meant Tor
According to Andy Yen's blog post (which is worth a read if you haven't yet), either would have sufficed perfectly fine. If Proton turned over an IP address for the emails that lead to a no-logs VPN, that would have been the end of the trail. Even if the user connected with Proton's own free VPN service, that would have sufficiently obfuscated their traffic because the IP address doesn't lead anywhere (under current Swiss law, email and VPN are treated differently, and Proton VPN cannot be compelled to log user data.)
Graphite If Proton were to start breaking the law to keep customers shielded, I'd leave. Because it won't last long and I'd expect LE to start infiltrating, spying and raiding.
I think this is right. For people who can be bothered to use the resources correctly, what Proton offers is an amazing contribution to the privacy rights movement. To sacrifice all of that infrastructure and tooling just to take a bullet for someone who was careless or ignorant with how they were using the services does not seem right. It's unfair to everyone who is being cautious and using the tools correctly.
