I haven't worked at Fly.io for months, during the entire time I worked there I never saw us provide to law enforcement any data that we weren't legally obligated to provide (all of it extremely boring), all such requests routed through our (annoying, expensive) external legal, and we had no facility we could have used to provide "SSH session logs".
The only interesting thing I can tell you about interfacing with law enforcement is that it's pretty funny to authenticate law enforcement people (they can't just give you a phone number to call them at).
I have no idea what this is about. Sorry, you're not going to get any tea from me on it!
