Which Google repeatedly vehemently denied. > I’m not sure I can say this more clearly: we’re not in cahoots with the NSA and there’s is no government program that Google participates in that allows the kind of access that the media originally reported. Note that I say "originally" because you'll see that many of those original sources corrected their articles after it became clear that the PRISM slides were not accur…
Which Google repeatedly vehemently denied. Probably because they're forced to do so by the authorities, like Lavebit was. So it becomes a question of who you are going to trust: Snowden (who has nothing to gain by lying) or Google (who is required by law to lie about it and risks losing a lot of money if their customers lose faith in them). I know who I trust in this case.
As i've pointed out in a few discussions, the law does not (and generally cannot constitutionally) require you to actively lie about something (IE compelled inaccurate speech). It can require you to not speak about something, compel you to speak truthful things (as a disclosure or otherwise), and require you to not tell someone something, but cannot require you to tell them something that is a lie.
AFAIK, Lavabit was forced to not disclose something to their customers, which fits in with what I said.
There are actually fairly important distinctions, legally, between different types of speech, and important legal distinctions between compelled speech and lack of disclosure. So you can't really paint all of these things with the same brush.
