I mean, OK, but if Windows's GUI (or PowerShell, or whatever) crashed or misbehaved upon update, would you be satisfied with "that's win32k/DWM/whatever being a poorly implemented mess; everything underneath should be solid"?
No. D-BUS is a travesty and blight upon the Linux desktop, and with systemd, every Linux system. It's the most fragile and nasty IPC system I've encountered. There are several better alternatives implemented by competent people, so there's really no excuse for its many defects.
Roger, I think we both know D-Bus has been rock stable at for the last 7 years, or possibly more, and Simon McVittie, its current maintainer, is a highly skilled and competent engineer.
While I find the situation different with systemd maintainers, whose communication style used to be questionable too often, and their software had some nasty bugs, I must admit that despite those problems they've also built software, which is nevertheless reliable, even though it took them a lot of time to come there.
This, honestly, is the most disappointing statement I read from you in the recent couple of years. And I'm saying this as a person who used to respect you a lot. I find your lack of respect together with the willingness to spread lies like this quite appalling.
