Oliver Samwer's response to the negativity being circled about him. http://www.idea-lab.org/videos

Also, I think it's a bit unfair to reduce the brothers to a "copy-cat" title. This happens everywhere, its just that they are the most successful at it. There are a lot of really cool tech companies in the valley that are relevant to non-english-speaking countries and developing ones but these countries don't fully benefit because the originators of the ideas pay no special attention to this countries. Mere providing different language translations does not breakdown the different albeit subtle differences between different cultures.

I think the samwers should be commended for what they do especially for their German market.
