Freedom to hack is the freedom most obviously applicable to educational applications, and you clearly arent getting that here. They ARE marketing it as a Free Software board, I dont know how I can possibly spell that out for you any more clearly. Read their marketing releases. They were bragging that this was the real deal, the most open driver blah blah blah and it's just not. It's worse than Nvidia. The entire driver has been moved to the GPU, and the GPU, NOT the so-called "CPU," is actually in control of the board! In effect it's a proprietary system which will run linux on a coprocessor so you can pretend, without even having the advantages that sort of a system could provide if it were done right. The more I look at it the more unbelievable it seems that anyone would actually buy it understanding what they are getting.
I hadnt paid all that much attention to this project prior to this story, and the more I look into it the more I have to ++ my earlier comment about the "negativity" people are decrying being a good thing on balance, because if I HAD ordered a stack of these things based on their marketing and found out the reality later I WOULD have to find a way to make sure they spent more dealing with me than they made on the deal.
