I hear you, although I respectfully disagree that my comment was either flamebait or a generic tangent. The topic is (IMHO) appropriate for HN, and a concrete example like this is a good way to highlight the issue. It seems quite far from a common weed to me.
It's generic in the sense that it masks out all the bits about fusion energy, let alone this specific report of a discovery, in favor of the much larger and more general topic of what's happening with science and health funding in the US.
