Granted, Microsoft et. al could attempt to lobby politicians to get these sorts of laws reversed, but that's not the position I was arguing against. Specifically, the GP said, "Do you think the government would jail someone of Steve Ballmer's stature if he talked openly about what the government has asked of Microsoft." That's an argument that Ballmer clearly could've talked about these programs because they wouldn't arrest him, but that assumes two things: a) Ballmer knew about this, and b) Ballmer was willing to take the risk that he wouldn't go to prison if he talking about that. Neither of those are a given.
Talking about lobbying is attacking an argument I didn't make, but I'll address it anyway.
From the standpoint of the big companies, lobbying only makes sense before the law is passed if you have no interest in following it. Alternatively, you follow it while lobbying to get it changed. You now have companies attempting to get the government to allow them to talk more openly about what they do with regards to PRISM and so forth. To put it in perspective, if SOPA had've passed, do you think Google et. al would've just ignored it?
