I have to respectfully disagree. They have unlimited financial resources, which translates into unlimited storage capacity etc. But NOT (IMO) unlimited technical resources in the sense of brainpower and creativity. When I say technical resources I'm referring to the ability to create new tools.

For example, I know for a fact that a large number of intelligence tools are written on top of open source projects. That base did not come from the technical resources of the government (in most cases) but rather the collective ingenuity of the hackers and programmers that built it for various reasons. You can already see projects springing up with the intent of circumventing government technical oversight. This is going to result in an endless game of technical whack-a-mole where one side is motivated by a paycheck and the other is motivated by ideals and the desire for liberty.
