Also, the author's full email [0] doesn't do him many favors; for a discussion of a project that purportedly consists completely of open-source and public ideas, there are a ton of redactions. Like:
> "You're right that the existence of ⬛⬛⬛⬛⬛ was initially brought to my attention by my work at Repl.it. But then again, it also shows up on lists of popular ⬛⬛⬛⬛⬛⬛⬛⬛⬛ for JavaScript."
I'm not a lawyer, but I simply just would not have written that first sentence. Hopefully ⬛⬛⬛⬛⬛ is something like "React.js", and the author is just being overly zealous in the light of Replit's legal threats.
