Your notion of open source doesn’t solve your problem of namespace-legal collisions and consequences. Azer has a Copyright on left-pad’s code. He /constrained/ that Copyright-protection irreversibly when he released the code under a Copyleft license. That says nothing however of the implicit trademark he has on the term “left-pad.” In fact, without even registering it, which he is free to do at any time, he has a local trademark that prevents npm from diluting it against his will.
Afaik, you’re in violation of those trademark protections which is the very thing you sought to get out by giving Kik Interactive Inc., “Kik.” It’s highly likely that Azer has less in the way of legal resources, but that’s the strength of your argument here.
