It probably depends on the level of the criminals and organized crime groups. I saw this Youtube video a couple weeks ago that talks about the history of how organized crime groups were using encrypted communication https://www.youtube.com/watch?v=gigIOc_0PKo (And how they were honey-potted by the FBI to use an FBI-hosted service, lol)
Organized crime groups that make 100s of millions should be capable enough to hire skilled developers and sysops to host self-managed services. At some point if they make enough money, investing in self-managed communication becomes preferable over using telegram or signal.
