What is this? Some crazy guy makes significant changes to a standard, the distribution maintainers will just gobble it up (as per usual) and then I have to weigh the pros and cons instead of complaining and fixing/adapting my systems e.g. wasting time because of a crazy guy's ideas?
There is no market in OSS. It's either use it or leave it. But even in OSS there are established standards which are relied upon! Poettering doesn't care about that, because he likes change.
Taking 5 year's to learn something new is your problem.
This guy has become the bogeyman of OSS. Does he have some sort of mind control that makes distributions pick up systemd?
Why is he crazy because he's suggesting change?
I don't understand your last paragraph. Did the guy behind systemd use OSS or leave it?
Instead, systemd solves a lot of problems for distro maintainers. The didn't just "gobble it up", they made a very measured choice to adopt it.
(I'm looking especially at udev and all the dbus hookery.)
