Some monks replied you with a link to a page in which Dominus suggests to boycott Amazon. There are also other people around the net who share his point of view.

However, you should also read Jeff Bezos' reply, which you can find in his open letter on patents. There's also an old Slashdot discussion around it. It turns out that maybe Amazon ain't that bad, but it's up to you to read and decide.
