It seems reasonable to disagree about whether companies should have the right to prevent forks based on their public data sets ("can you fork the phone book?"). It does not seem reasonable to suggest that Craigslist sued simply in order to be tyrannical.

Or, for that matter, because somebody was using up their bandwidth, which is a finite resource, for something other than the intended purpose of the site.
To focus on the act of scraping itself, consider a case where they download the data and study it privately. That should not go to court, even if they broke the ToS, unless there are measurable damages.
edited: this said "for 3taps" before, but I'm not sure that's accurate.
I like your analogy of the site being forked. I don't believe for a 2nd that the companies scraping the CL data and putting a pretty UX on it were doing it out of any sense of altruism.
You're saying this because Techdirt is manipulating you.
The CFAA is in fact the logical private cause of action for suits to enforce terms of service. It is literally the section of the US code about enforcing ToS's.
A civil suit is a civil suit. CFAA-derived civil suits are not especially more scary than other civil suits. It's scary to be sued by Craigslist no matter what. The CFAA has nothing to do with it.
You should be irritated at Techdirt for misinforming you solely to generate rageviews.
You'd file criminal charges against someone who breaks into your home every night to hurl racial slurs at you and keeps picking your lock no matter how many times you change the locks; why wouldn't you file criminal charges against someone who comes on to your channel/forum/etc. every day to harass your users and uses a number of proxies to change their IP no matter how many times you IP-ban them?
I can easily imagine a public irc channel that ip blocks abusing users that post goatse links (not illegal in itself). If some of those users than bypass that block, is it unreasonable that the owner would want to sue in order to stop the abuse from the then unauthorized access to the irc server?
