I didn't mean it to be haranguing, but OP was giving what amounted to legal advice that was actually wrong and dangerous. I do think that needs to be called out and clarified—not as a personal attack on OP but just as a matter of safety for readers.
I'll acknowledge that kstrauser may have done a better job of sounding friendly about it, but I don't think my question was out of line nor even particularly aggressive given the circumstances.
I'm sorry to press the point, but I don't think you're correctly assessing the impact of comments like your GP post, especially on a legit new user like lossyrob.
You may not have meant to be haranguing, but intent doesn't communicate itself—at least not in the tiny textblobs which are all we have here. It has to be included in the message.
When I look at your comment from that point of view, I notice that it leads with a hostile personal trope ("You do recognize...?"), followed by a putdown of everything this team is probably hoping for ("no one should use this"), followed by a personal attack ("you shouldn't be encouraging"), followed by a pedantic hammer-blow ("legally the license is the license") that takes the spotlight away from anything new or exciting about their work. That is followed by a sentence that basically shames them for what was obviously just an oversight. How is a newcomer (or anyone, for that matter) supposed to feel when they encounter that?
You're a good HN member and I'm sure you didn't intend to condemn or humiliate anyone. The problem is that people routinely underestimate the provocation in their own comments and overestimate the provocation in others'. If the error is 10x in each direction, that's a huge skew [1]. That's why it's hard to track the impact that one's posts have—especially the righteously indignant sort of post [2].
I suppose one of the moderators' jobs is to step in and try to articulate that explicitly, in the hope of persuading enough users to generate a bit of a system correction.

[2] which, by the way, I can feel a bit of in my own comment just now, and I'm probably underestimating it too.
OP was giving what amounted to legal advice
That is a huge overstatement that you can't really use to justify the haranguing. They just popped in to address the potential issue and let people know they're trying to sort it out. Nobody is giving legal advice and nobody is going to end up in legal trouble because Microsoft messed up their license boilerplate for a bit.
