No they don’t. Clearly an open-source module and a chat product are two different lines of business. They wouldn’t have lost their trademark because of this.
The polite attitude in open-source is to accept that the name belongs to whoever “homesteaded” it first, and that an open-source module is just as serious and just as important thing in its own right as your legally created business.
Kik WERE being dicks here … preciously demanding that they just had to have their own name and couldn’t possibly get by with “KikChatLibrary” or something. As dozens of other companies do.
Instead of negotiating or seeing the existing developers’ side, they immediately claimed a spurious legal justification and threatened legal action.
Just because they didn’t swear doesn’t make their tone any more polite or acceptable.
