I don't think it's 'conspiracy' what the government's doing, they're behaving like every person and corp. Simply using legal and financial tools to get what they want.
1) Telecoms granted immunity.
2) Quest CEO claims retaliation by NSA for refusal (old)
Here's my point in relation to Microsoft: That having won the case against MS, the DOJ had them 100% 'bent over the barrel' as it were. And in exchange for their continued assistance to the NSA, they were granted the 'consent decree' as a sort of 'released on probation', rather than breaking up the company at that time (or imposing other really draconian measures). As with all of the other secret FISC/DOJ agreements, just enter one for MS in relation to this case. MS would certainly have agreed to go along. Besides, monopoly is good for state control and Linux as an alternative would have looked bad to the NSA too. Method, motive, and opportunity.
Look what the facts of the case with the Quest CEO. The loss of the NSA contract (and the related mis-measure of income/profit as a result) directly created the situation he was charged with. I suspect that the government came to him looking for him to go along with the plan too. He didn't want to play ball, and when he tried to cash out and run away...they got him for insider trading. What's conspiracy about that? Method, motive, and opportunity.
Look at the ongoing investigation of Google now too. Not claiming that they're innocent, but DOJ gaining leverage with an 'ongoing investigation' of something or other is just their style. US Government wants into everyone's pants, any time they want too.
People did used to say I'm wearing a 'tin-foil' hat, but it's looking like the 'high fashion statement for 2013' these days.
