Dan DeFilippi: "In my unhumble opinion censorship is never an option."
Dan DeFilippi would certainly not like it if all his documents and code from his personal hard drive were splashed across the internet.
What he considers "censorship", another person would call "not pushing someone in front of a train". He knows full well that (a) Dropbox is a pretty friendly company with reasonable people solving a real problem and (b) the RIAA and MPAA are NOT friendly and NOT reasonable.
This linkbait title ("kill open source project") is the equivalent of police going after students for bike tickets while avoiding the dangerous parts of town. Dan DeFilippi is going after the good citizen (Dropbox) for the minor philosophical crime of not supporting everything that calls itself "open source", while completely lacking the balls to actually take on the real bad guys here, namely the RIAA and MPAA's real lawsuits.
Indeed, even if he did set up his own torrent server, they'd ignore him for a while. Dropbox has financial resources, so they'd actually be the target. So DeFilippi is getting behind them and trying to push them in a fight that is certainly NOT one they want to engage in, without taking any personal risk himself. Not particularly ethical, IMHO.
