The problem I see with any complaints about Lennart's behavior is that his behavior is explicitly rewarded. No one is really "routing around the damage", unless they're taking the dysfunctional route of ignoring problems with the software. Lennart has been "crowned" with the position of being the de-facto leader of Linux init systems, since just about every distro that matters at all has adopted systemd. So unless the Linux community is going to adopt something different, or fork it and have some different leadership, I don't think they have much right to complain about Lennart's communication and leadership style. Don't put someone in a position of leadership and power and then whine that they're not doing things the way you want them to, unless you're prepared to back up your criticism with real action. The Linux community has apparently decided they're going to use Lennart's creation (and not fork it away from him), no matter what, so what's the use in complaining? People have been complaining about him for many, many years now, and he's obviously not going to change.
This reminds me a lot of everyone complaining so much about Windows 10. If you're not prepared to vote with your feet, your complaints are just wasted breath (or keystrokes) when the vendor obviously doesn't care one iota about your grievances.
