I certainly believe it's unconstitutional but as an non-expert I think the courts feel skeptical of that argument (I believe they argue circumvention is conduct and not speech), and are perhaps less likely to review such cases because they feel it's unimportant. I'm hopeful about the EFF litigation though.
