God. OK. While I agree with you in many things, there are a few things that you seem to have missed:
1. Debian (or general-purpose Linux generally) isn't simple anymore. These days are over and there's no way to get them back. Really. This is true for EVERYTHING in Debian/Linux and in every other OS. General-purpose systems tend to become more complex to be more easy on the outside. And there's no way around that.
2. The "community". I don't even know where to start. The "community" has turned into a mob that knows everything and gets nothing done. I'm sick of that. Strong opinions about things with no alternative implementations are worth exactly nothing.
3. Sit down and develop something better and defend it.
4. There is no step 4.
Meanwhile I really fear that several community-based projects will happily fail just because there are legions of people who know perfectly what they hate and have no precise idea what they want to have or even would sit down and DO IT. Do I like SystemD? No, it sucks, just like every other comparable system. Do you know what I hate even more? Not having ANYTHING to work with and to rely on it staying around.
Debian (and Wikipedia by the way too) is becoming a bit like a failed state: Factions that love fighting more than building something and kill each other while there's hardly anything left than smoking ruins around them. If there's someone doing something that you don't like and won't listen to you than either just sit down and do something better or shut the fuck up.
Debian is becoming a lesson in applied entropy.
