I suggest rallying around vendors like this: https://www.crowdsupply.com/pu...
Honestly I think those guys are a bunch of hypocrites. They make a big deal about openness and evil binary blobs etc. But last I checked I don't see their board design schematics, layout files, CAD drawings for the chassis, etc. available anywhere under an open source license. They make a big deal about needing open source to foil NSA backdoors... what about NSA backdoors baked in to the board design? A covert NFC chip can violate privacy just as easily.
Moreover, even if you had all the source code for every single byte of code, how can you trust the binaries that were pre-installed by these guys? Should we really expect every end user to recompile everything and crack open the case and use a flash programmer to reflash everything (flash programmers are spendy by the way.) Also, even if it is open source we won't find all the security vulnerabilities in the code anyway (see heart bleed.)
Call me crazy, but I respect IHVs wanting to have the ability to patch hardware issues on devices that have already shipped. Remember the Pentium FDIV bug? Intel has had up-datable microcode ever since then for a reason. Having hardware be patchable like that creates binary blobs of out necessity. I guess I'm just too pragmatic or something.
