I have not experience with Saintsmart products and after brief look at their page I cannot say they sell fakes but clones. If we are talking about HW, especially UNO R3 which looks the most close to original Arduino design. They are not use Arduino's trademarks and since this moment for me it is O.K.
SW is open source also except Arduino USB VID which is paid but I have no idea if they use own or what.

They are selling a board that is manufactured to look identical to a genuine Arduino. Doing that violates the Arduino trademark.
Sorry, I cannot agree. Identical look but with their own logo. It does not violates the Arduino trademark. Provide some evidence.
