@Kevbert this isn't an airport, you don't have to announce your departure.
But I don't understand why you updated to a beta (public or developer) if you weren't prepared for things to be broken. That's the point of the beta, so find and identify problems with the OS and apps you use.
It sounds like you updated your main computer - that's a bad idea. You should update a secondary computer for testing, if a piece of software being broken is going to be a big deal for you.
The other option is to downgrade if you find something that completely blocks you.
But instead you've gone for the antagonistic, aggressive option of bullying the developers of this software.
