The IRS of course! D'Oh, McAffee must really be a dopehead to not have figured it out: Imagine if every rich entrepreneur were to flee taxes by moving to some Caribbean or South American tax haven. That's the IRS's wooorst nightmare. So in order to prevent that, they have to make an example so that the others who are flirting with tax motivated expatriation fantasies are afraid and prefer to stay and pay.

It's funny how Bennett thinks that the release of diaspora as open source would be a step forward towards the success of that platform. The sad reason behind that release is that the money is out and the developers don't see a way that diaspora would give them any income, so they couldn't continue working full time on that project and had to move on.

Of course, they're not gonna say it's dead but "release it as open source" (after all, some other guys could continue the work, right?) but there's not gonna be any full time core team behind the project simply because it's not a viable model to pay the rent/mortgage.
IIRC, the initial funding about 2 years ago was about $200000 for 4 devs. That's $25000 per dev per year. It would take a lot of idealism to continue working full time as a dev for that money, and even more so for $0 now that that money is gone and there's no income in sight.
