Has FCC chairman Julius Genachowski changed his mind on the acceptability of data caps? As far back as 2010 he defended the idea of wireline ISPs using broadband usage caps as part of the network neutrality order and did so again in May at The Cable Show when he reiterated the position. The chairman has said he doesn't mind the caps and is in favor of ISPs having the opportunity to experiment with different business models, but last night at a Silicon valley event it seemed like his mind has changed.
