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.
