Your point is that removing the logo from the reference design will eliminate fake boards.
No, that is not my point.
First, this is open hardware. That means there are no such things as fakes. Anyone is allowed to copy the reference designs and sell them, give them away, whatever they like. The only thing they are asked not to do is use the name Arduino.
Now, I do not know if the originators ever officially copyrighted or registered the name. My guess is that they did not. However, in the US and Canada, they will own the copyright anyway. Not sure about the the rest of the world.
So, second. If they reserve the use of the name Arduino for their own boards and publish the reference designs with a 'Design by' message, then those honest folks that want to produce their own boards from the reference design can be identified by including that message. So that we, the consumer, can make a decision to either buy and original, or buy one displaying the message. The originals can easily be identified as coming from an authorized source.
Then there will no longer be any incentive for anyone to put the name 'Arduino' on their boards.
Most of the items that come from the far east that illegally display the name Arduino are that way because the published reference designs include that. They just send the Eagle files off to the board maker. They are lazy, and if there is no reason to alter the files, they won't. Like most people trying to make a buck, they won't go out of their way if there is no clear advantage.
This is what I meant.
Now, I don't care if this makes sense to you or not. I wont argue the point with you further. You are entitled to your opinion as am I.
