You don't care how other people build their systems, or you do? Which is it. You agree that you don't care, which is obviously the correct answer if you're not trying to strip our freedoms away from us. But then you give a bunch of reasons that seems to be some sort of "but" and where you do actually oppose letting us make our own choices, on account of other people are making the same choices as us, and those people's choices have more impact in the world than your own choice.
Making your own choices doesn't guarantee you the right to be in the majority; if systemd is so bad, you'd have no trouble convincing distros not to use it. Maybe the failure is in the argument; maybe none of the people whining are actually having systemd forced on them, and maybe none of them that are using it are being harmed by it, either.
BTW dbus is the newer, higher level IPC mechanism. If you're whining about the fact that dbus support will be guaranteed to be present in modern systems, that is a losing argument. Anybody with SysV IPC experience knows what a PITA the old ways were; it was so bad that people would write custom networking protocols for process communication instead of wrestling IPC. dbus solves real problems, and if you choose it or not, it is obvious that it is a necessary part of the ecosystem.
I use skype a lot, or rather my wife does, it is the only proprietary software that I rely on. Entirely for their foreign POTS integration; it is way cheaper than international calling cards. I had been totally non-proprietary for years before signing up for their calling service. They did indeed switch directly from supporting both ALSA and OSS to PA-only. You can't blame PulseAudio for that. You just can't. Skype isn't open source, and isn't developed by Poettering. You blame him, by name, for something done by Microsoft programmers, who likely didn't consult him. That is really lame, and you owe everybody an apology for that pathetic drivel. It is rather obvious to everybody that the users would be better off if they had added PulseAudio support and continued the ALSA and OSS support. Skype is really buggy and their auto-levels system will screw up all the system audio settings; it is more reliable to set Skype to OSS support simply because that minimizes the audio capabilities that the low quality client code can try to operate on. The good news is that after turning off the auto-levels feature, the audio works fine.
