"They all do it" is not a compelling argument. The Latvian state surveillance potato is about as much a match for the NSA as Latvian air power (two unarmed helicopters) is for the USAF. There are places that have very low levels of surveillance simply because their governments, no matter how perfidious their intentions, haven't got the gear.
They're not using those helicopters to fly Stingrays over Riga. That would burn the whole spying budget in a week. Compare that to the number of PDs in the US that have multiple aircraft that, in fact, are flying Stingrays around collecting our whereabouts.
We are objectively less free, and have vastly less privacy, than many other countries. And for what?
