They seem to have antagonized a lot of security researchers and engineers. So like, there are people that are now coming out. Very well known Bitcoiners that are coming out and saying like, yeah, I tried to talk to them because they didn't understand the code base or I'm trying to understand the code base and, you know, they were dicks. So I didn't like keep looking or whatever.

You have a complex code base, a small developer team.
