While I agree the EFF should be concerned with companies asking for exclusive licensing to user posts, because its mission is to protect individuals' digital rights, I don't see why it should concern itself with whether companies make aggregate data cacheable, scrap-able, or API-accessible to other businesses.
CL makes money by aggregating data: it attracts buyers by aggregating all local listings in one place, and it attracts sellers by aggregating customer searches for local listings in one place. IMO the EFF has no business asking CL to give its product -- aggregate data -- away for free.
Please explain, how exactly is the EFF "tap-dancing" here?
