As Don pointed out, it's the threads that have been clipped, as it were, not the topics: I think it's probably just as well, as those threads themselves were started by either a sockpuppet or someone who had lost control of himself, and the threads were counterproductive.
So I can say, "systemd!" here,
And this post will still not be blocked.
