I'm sorry about triggering you. I can see your point. I did not mean to focus attention away from what happened and how to avoid it.
I am sincerely interested in seeing if the HackerRank leadership will reach out and discuss. I was not intending to promote anything I'm doing right now. I suspect they won't but I will talk to them respectfully if they do.
Let's promote the SymPy maintainers, though. Let's also promote NumFOCUS, because they do a valuable service to community-driven projects and could help SymPy respond to this sensibly. Let's also promote NumFOCUS because they efficiently and tirelessly work to help the projects they fiscally sponsor (like SymPy) -- providing legal support: https://numfocus.org/.
Perhaps something good can come out of this, still.
What are you doing about all the other bogus DMCA claims you company has sent (itself or via its external contractors)?
What are you doing to ensure this never happens again?
Why should we believe your answers, and how can we see concrete evidence that you've stopped doing this and made up for all the times you've done it in that past?

Multiple commenters asked him this and he never replied.
Disappointing but not surprising. It's all just superficial hand waving. They are sorry but only for bring caught.
