So, to quote the subject of [1]: "call for votes on default Linux init system for jessie" Note that it says "default", not "only".

Where does that support the claim that Debian would oppose people working on sysvinit support?

What did "Debian" say exactly? Can you link it?

Or are you just stating what you imagine "they" might have said? :)

It might also point into the direction that the people behind Devuan have never worked on a distribution before and needed quite a bit of time to figure out how stuff works.

You might want to learn how shared libraries work under Linux. Then you might be able to understand why packages have a Depends: libsystemd0 (which btw. doesn't depend on systemd itself).
