Yes. I broadly and specifically oppose measures designed to reduce our privacy, or to grant the government warrantless access to our emails or communications. But at the same time, the insecurity of critical systems in the US is a real problem, and it is reasonable to assert that it demands some kind of intervention, and thus to measure proposals like this by how much of a dent they put in the problem.
As it happens, the privacy impact of this EO and of CISPA are minimal. The privacy impact of the Lieberman-Collins act is marginally greater, but the market impact of it is much worse, and I anticipate that it would do a much poorer job of addressing the problem.
