I don't think it's fair to describe it as a veil either. Preventing customers from being misled is the entire point of trademarks. Someone in another thread used Cocacola as an example.. so imagine if someone took Cocacola, added some ingredients, and started selling it as Cocacola... that's pretty clearly trademark infringement. And that's exactly what they're doing here.

I have to wonder why they even modify it.. Ubuntu has great hardware support in my experience.. and they release cloud and server images exactly for this purpose. Completely free.
