No disrespect to your question - it is fair and reasonable - but why is the top comment on a post about Thunderbird's Matrix integration essentially a tech support question about a completely unrelated thing in Thunderbird?
Because it's a niche feature barely anyone will use or is interested in using and so they have nothing to say that would be on topic. But, this being HN, people still use the post to piggyback on with their issues or requests regarding Thunderbird in general.
Actually, this happens faily often. Each time some popular project gets a post like "php 8 released", "net 6 released", typically, what should be discussed is the theme of the release, new features, changes etc., but what the top posts end up being is just people arguing how php is shit and java/kotlin is better than net yadda yadda. Seems to be natural in open discussions, also happens on Reddit.
