Well, it’s pretty simple, did Azer name his open source project before Kik Messenger had their trademark? If so, he legally owns it because of common-trademark law rights, if not, he doesn’t own it.
What a great idea, why don’t I write a bot to scour popular brands and preregister names on places like reddit, github, npm, et. al., then extort the brands for money if they ever want to use them!
Obviously this isn’t what Azer was doing, but if he didn’t have the name first then he shouldn’t expect to be able to hold onto it.
