His career is over, and this is how it should be. Plagiarism is very hard to find and prove, but once there's no more doubt, heads roll. It's the only way to send a clear message to the ones who haven't been caught yet or who simply toy with the idea of doing it.

I really hope they'll make the auto-updates more aggressive, like Chrome does. Otherwise, the Firefox market share will become excessively fragmented.

Most of this has been the work of Jacob Appelbaum, core member of the Tor project. He is the one who investigated the fraudulent certificates and it's a fascinating detective story.

1) It's Tor, not TOR.
2) The project is alive and kicking, check this blog to see for yourself: https://blog.torproject.org/
There's a lot of work to do on Tor, Vidalia, Torbutton (so much more than a proxy switcher, stop using Foxyproxy for Tor, FFS!) and the various bundles offered by the project. Translators are always welcome.
3) Lots of new clients (Iranian or otherwise) means a greater strain on the existing infrastructure. This is hardly 'revitalising' in a network in great need of bandwidth and exit nodes. Of course, dissidents using it is a good thing, it's part of why Tor exists; I'm just pointing out the inaccuracies in the article.
4) If you want to help the project, please dive in the code, donate or consider running an exit node.

Is Freenet ready? What do you mean they're still coding it in Java?
