To be fair big tech did do a full court press to stop site blocking when such a law (SOPA/PIPA) was proposed in the US, and they continue to oppose the MPA's attempts to get site blocking via the courts. DMCA on the other hand seems very broken, don't give the MPA the "3 strikes" regime they want and you get sued into the ground like Cox. I suspect tech CEOs don't complain about this because they don't want the same treatment.
