She has supported NSA collection of information on all citizens of the US. There is no reasonable argument for this and it's not even in the same universe as search warrants.
I share your opinion that the NSA's surveilance is bad, and I'd assert it's unconstitutional, but the hypocrisy/contradiction you're trying to highlight still isn't necessarily there.
The government can kill me; Facebook cannot. The government can imprison me; Facebook cannot. The government can require I pay taxes; Facebook can not.
It shouldn't be surprising when similar disparities exist on surveillance. The NSA's program has yet to be deemed unconstitutional by the courts, which is what matters.
