'While it's impossible to know whether or not Amazon's decision was directly caused by the call from the senator's office, we do know that Lieberman has proposed "anti-WikiLeaks legislation" and that he has a history of pushing for online censorship in the name of "security."'
But then for the rest of the piece they make strong statements assuming that it is true:
"That makes it all the more unfortunate that Amazon caved to unofficial government pressure to squelch core political speech. Amazon had an opportunity to stand up for its customer's right to free expression. Instead, Amazon ran away with its tail between its legs."
I wish they'd found a more honest way to make their point than innuendo. They could have at least kept it as a question for the reader to answer in their own mind.
