Well, as someone who should understand the value of free software, it is kind of your fault for buying a part from a company who has never supported foss before, and this move is quite a change of pace from them.
If they pull an AMD, except they do it right (ie, just depreciate the proprietary driver for enterprise compute usage and focus entirely on making gallium great) they have my business forever.
I'm thinking of getting a tegra note next month, on the pretense that at least Nvidia provides open source Tegra drivers through a 3rd party so that the platform is hackable. The new Nexus 7 is a disgrace since smart people have to waste their time reverse engineering the gpu in the Snapdragon because Qualcomm is being a dick.
