I am not surprised by the hypocrisy of the US government here, but where is the proof? He doesn't directly link to the June 2010 report to back his claims. While I trust him, the critical thinker in me despises not being able to check sources.

Maybe the reason you're not surprised is because you've heard this story before.
We learned last year that the NSA has an "interdiction" operation to intercept hardware en route to its destination and install monitoring devices or malware.
For example, here's a Der Spiegel article from December 2013 [1]:
If a target person, agency or company orders a new computer or related
accessories, for example, TAO can divert the shipping delivery
to its own secret workshops. The NSA calls this method interdiction.
At these so-called "load stations," agents carefully open the package
in order to load malware onto the electronics, or even install hardware
components that can provide backdoor access for the intelligence
agencies.
