Clearly? Really? There is nothing in the slightest clear about it.

That's exactly what makes one suspicious.

It could be anything embarrassing or that would be dangerous/costly to talk about. Government interference is only one possibility. Maybe a competitor paid them to shutdown. (probably not, but it's possible)

When in doubt, assume it was the NSA. That's a safe assumption to make any time you have no knowledge at all.

I'm going to start blaming them for the weather.

I've got no evidence that they're controlling the weather, but it seems like something they would do if they could.

actually it's provable that the weather is partly controlled, at least in Germany. http://www.br.de/themen/wissen/wetter-meteorologie-rosenheim... No need to be a conspiracy-theorist, it's simply true. They use that to avoid hail damaging the crops.

They clearly can manipulate the weather, the question is to what degree and when do they do it and with what aim: http://en.wikipedia.org/wiki/Weather_modification

Yes, that's my algorithm.
