as this was my post I just removed it because I suppose you don't know what comes of these things from the legal side. I'm located in Germany and I don't know much about international brand laws but even if they don't stick I don't want to be cause of offence to the people at Claris or the agency that designed the logo. That's what jormonds - since deleted - post reminded me off.
Point is: I try to not fuss around with other peoples designs, there is always something personal to it. I suppose somebody put a lot of work into this and there has been some discussion internally going at Claris incoporating even more people. Since I'm a craftsman and architect and now doing UI and all this stuff in my third professional life I would also be somehow bothered by people fooling around about my ideas. I'm always ready to discuss my design but if I am not allowed to take part...
So thinking about it it's more of a decision taken in relation to the respect for other peoples work. Always time for a second thought on things or at least I hope so.
