There was a discussion on reddit about this where one user emailed them asking about bitcoin and they said[1] that:
>The EFF has a great statement[2] on BitCoin that closely follows our feelings toward BitCoin
But someone from EFF said, allegedly, that they will reconsider accepting bitcoin because:
"It is possible that the legal and/or technical landscape has changed enough in the last couple of years for us to reassess our stance on taking BitCoin donations." [3]
