Which part? Andreessen taking his anger out on Snowden or the NSA's tampering? To the latter, yes, yes I do. If for no other reason than the consequences of such tampering are obvious if ever discovered and nothing ever stays secret forever. They made the decision and we can only assume they did it knowing full well what would happen should it ever come to light, leak or not. Would things have been much different if this was discovered 5 years from now? How about 10? Can we assume they would stop tampering with equipment at any point without disclosure?

IMHO no agency that is being funded to fulfill American public interests should be making choices that override, or put at serious risk, the needs of the public just to make their job more efficient/effective. Even if we accept reinterpretations of what public "needs" might be, this was a decision who's risks would be extremely costly should disclosure ever occur and it shouldn't have happened, perhaps even outweighing the benefits (to the public) they offered, which we may never get a straight answer as to what they were.
