But Germany, at least, is happily cooperating with the NSA. And didn't Poland host CIA black sites?

Both have nothing to do with SIP surveilled through black boxes and intelligence agents being cleared to destroy informatic systems.

I can't imagine a government finding black sites completely acceptable but balking at global Internet surveillance. As for Germany, it depends on how closely they were cooperating with the NSA and how much they were willing to invade the privacy of EU citizens.

I think it'd be more pertinent to see what was the reaction of Polish people to a perceived attempt at limiting their Internet freedom in 2012:

Keep in mind that the memories of communist censorship are still quite vivid, and so the electorate is quite sensitive about any kind of surveillance.

On the other hand, keep in mind that the corollary of "law on mass surveillance purpose-built to legalize existing practices" is that French citizens are already "benefiting" from secret mass surveillance (emphasis on secret). Unfortunately, it is extremely difficult to prove or disprove the existence of a similar effort in Poland. Whether the population agrees or not is irrelevant if elected officials conspire to keep them in the dark about it because security.
