I thought it was very well-known that Lucky225 made that story up as a cover to hide the fact that he gained control of Adrian Lamo’s @6 Twitter via a SIM swap hack himself, and also took control of Lamo’s Facebook in order to hijack ownership of the 2600 Magazine group on Facebook.
It's a very awkward thread where Lucky225 accidentally demonstrates that he has indeed taken over Adrian Lamo's email account. Note this doesn't say anything about whether they were or weren't friends. They definitely had overlapping interests.
Lucky would criticize Adrian behind his back all the time, and Adrian knew about it. They were rivals at best, and frenemies who barely tolerated each other in public at worst. Lucky’s the kind of guy who’ll toss someone right under the bus as soon as they’re no longer useful to him, but feign friendship until then.
