And you want utmost security for your body, which is why you go to the doctor instead of self threat. And also doctors go to other doctors when they are ill.
The sad reality is that things are complex and you probably get suboptimal results trying to do everything yourself, what other spend their lives trying to accomplish the same.
WhatsApp scaled to 1B users with only 50 engineers, but there were 50 people working full time to provide what people think they can provide in their spare time?
Also as the other end of any communication is quite scaring thinking I am communicating securely with someone, but then finding out that their server is compromised because of an out of date library or service.
If you've ever used Docker or deployed an nginx server - then you can very easily deploy a chat server. Pretty much the same thing but over a different protocol.
Server getting compromised - that's largely unimportant with end-to-end encryption through OMEMO. Distros also apply security patches (just keep things up to date).
You do not require 50 engineers to run a chat server for <200 of your friends. In my experience, once you have the software configured and running - it pretty much runs itself.
