Funnily enough, today I have been working on an android app at a small startup which is also called Silk internally.
Namespace collision isn't that bad in practice. The UI of Firefox has been called "chrome" in the source code since long before google chrome existed, for example. It looks like it still is:
The name Chromium was playing on the fact that it's the metal used in chrome plating. (Just as the Chromium Project is used in making the browser Chrome.)
Google needs to start running this stuff by me.
