There are two things that are really, really wrong with what Kik did.
- Azer’s use of ‘kik’ is in NO way a violation of your trademark as what Azer is doing is in a fundamentally different field-of-business (cf. for example http://www.wipo.int/wipo_magazine/en/2006/06/article_0007.html). You had not right, actually, to be pushy about this.
- You are now asking a LOT of people to have to go back to their packages and look for ‘kik’ and rename it to something else. This would break the benefit of the entire open-source package system if people have to continually/constantly maintain their package listings. Brilliant move.
It would have been just as easy for you/your-people to spend the time (I’m assuming less than 30 minutes) to come up with a package-name that would be just fine - one that included your trademark (“kik”) and another word or two that would actually define what it is your package concerns. And it would still be just as easy to find your package. Instead, you chose to spend all your time being unbelievably rude to everyone who is currently using the ‘kik’ package. Your publishing the email thread above simply proves you are rude or, and I mean no disrespect, not very bright when it comes to open-source software (in the context of package-management in-particular).
The thread above makes you look like you are much more interested in your trademark than the good of others, despite your opening paragraphs. As they say, actions speak louder than words.
The push to get Azer to change the name of his package is still an abject failure on your part. This post of yours changes nothing nor does it any way change the opinion people have of what you did.
