What is common between somebody hacking a movie studio to stop the release of a critical movie and somebody killing some cartoonists in Paris. Both are examples of terrorism (one digital, the other physical)
Both deny your freedom to laugh at silly stuff.
This is the same reason I deplore denial of service attacks on websites that are critical to your ideas ( with the possible exception of paedophiles). Terror recruiting websites should be monitored by analytics not shut down by attacks.
The difference between the good guys and the bad guys is not just the reasons they do nasty stuff, it is also in their methods.
The internet needs more freedom not more regulation. Attempts to do so shall just cause activists to create technology that bypass future web anaytics in a more damaging way that current Tor projects do.
