Maybe, but the same argument could be used for other open-source apps. "Oracle could just grab the source code for MySQL", etc. Incidentally, this is one reason the GPL can be a big win. What you described happened to X, which was under the MIT license. It worries me that so many web technologies are MIT; it's so much easier to co-opt them. There is a web version of the GPL called the AGPL (http://www.fsf.org/licensing/licenses/agpl-3.0.html http://www.fsf.org/licensing/licenses/agpl-3.0.html). It's a pity it's not more widely known.
