This. The whole Linux community seems to be paranoid. It has to be a grand scheme, a plot to take over Linux, a conspiracy to kill "the UNIX way". Maybe it's just a group of guys solving their problems.
I don't see how anything of this is really Red Hat's "fault". Seriously. They develop a piece of software which solves their problems. They also incorporate projects they already maintain to improve functionality and make developing things easier. It's their projects, they're allowed to do that. The code is still open. It's not like everybody (Debian, Ubuntu, SUSE, etc) didn't have the ability to fork udev.
Yet all these projects chose not to fork the projects incorporated by systemd. Reason (1) might be it solves problems for them as well. There's no need to fork something that perfectly works for you. Reason (2) might be they don't have the resources. But that's a declaration of bankruptcy for the whole "Linux is built by community volunteers" thing. The people advising against "corporate influence" are not able to do anything of value in modern computing anymore (I'm well aware this is over-simplification, please bear with me). Requirements for software have changed. It's not 1970 anymore. And while the "old-school" users and devs are complaining about systemd & co, the "youngsters" are busy changing the ecosystem.
