1) As "just a fact" it's irrelevant. With some interpretation added, it contributed something. However...
2) As participants in a market economy, the lawyers' primary interest may not be the letter of the law or what is theoretically winnable in court, but what will give npm the least hassle. I'm not sure if that's the case in this particular trademark case, but we all know lawyers sometimes do counsel the path of least resistance. And maybe that's even wise. But it's worth being clear about that ambiguity, rather than just saying "lawyers said it, I believe it."
P.S. I think your comment isn't super helpful but I didn't downvote you.
That is why the law should be formalized such that correctness proofs for argumentations can be given and in doubt even be checked independently by a computer. Exactly because of the possibility of different opinions and wishes, coming up with such a high standard should be considered a maxim.
Perhaps you could start with this: to formalize any set of laws and criminal procedure similar to the actually existing law, you'll have to define knowledge, and that is a quagmire (http://www.unc.edu/~ujanel/Gettier.htm--you don't have to read the entire paper, but at least read the first section for a feel of how nasty the project gets. If you need more background, here is the description of what the Gettier problem is: https://en.wikipedia.org/wiki/Gettier_problem).
I know that the Moon is about 400,000 km away from the Earth. I have never measured the distance and I haven't even tried to check if it's plausible: I read it somewhere and accepted it as such.
That is rather an argument why in doubt one should not put such harsh punishments into the law - a thesis which I support.
As far as I know this is a mostly done problem (google "statistics").
Which means if they say "it's very serious threat" and the code gets deleted everybody would think they are serious lawyers even if the claim looked ridiculous - because you see, lawyers said it's serious and who are you to argue?
On the other hand, if they ever say "it's ridiculous" and then they get sued, they could be fired or at least suffer damage to their reputation for not preventing it.
Thus, there is exactly zero incentive for the lawyers - at least ones acting purely according to near-term incentives - to ever take even a minimal risk and declare anything like that ridiculous. They have all incentives to always react as if it was 100% genuine infringement - because that costs very little and has no risk.
Some lawyers and companies are more civic-minded and reject some ridiculous requests and take risk because that's the right thing to do. But you can not require people to be heroes.
On the other hand, we are not lawyers, so we have all the incentives to proclaim how ridiculous the whole thing is.
Pursuing a NPM package names?????? for real?!
If you've ever worked with lawyers you would have known that they would always be on the conservative (safe) side without understand the business implications.
It's only a matter of time until NPM is socially engineered into replacing a module with something more malicious, if it hasn't already happened.
EDIT: cool HN, -2 for stating a fact. Sure, I don't disagree that this lawsuit is kind of silly, but npm's laywers don't think this suit is _frivolous_, which is what matters.
