I'm not sure you are right. There seem to be an awful lot of lawyers phrasing it less clearly.
Trademarks require constant vigilance. The moment you let your guard down, there's a chance that someone else might swoop in and use your trademark without permission. This unauthorized usage could lead to confusion among customers and weaken the association between the trademark and the company it represents. Therefore, defending your trademark should be a top priority.
This might be done on purpose of course to attract clients.
I don't think kik was worried about that. It's more likely they were bullying the guy into giving up the package name.
That might be true regardless of copyright law :)
Thanks for your reply. I'm inclined to believe you, as it seems more likely that this was a case of corporate bullshit and not a case of "alas, our hands are tied".
