During the first half of the article, for example, he notes that the Kindle programs did not violate the ADA because they did not force any student to use a Kindle, and allowed them access to alternative materials, including (presumably) more accessible media.
I'd hardly call that "libertarian bullshit". (Indeed, I suspect the author would be less offended by your characterization of his writing as "bullshit" so much as he would "libertarian": http://en.wikipedia.org/wiki/Byron_York)
My chief problem with the article has less to do with York's premise (which seems to be that this was an example of horrifically inane government overreach) and more with York's overt sensationalism-- he himself points out that Amazon has already produced a fully-accessible Kindle-- why then the breathless article? Isn't the overt stupidity of the CRD fairly moot at this point?
Moreover, who wants to read a textbook on a Kindle?
