That's painting with a fairly broad brush. A tiny minority party - UKIP - have made it their main objective. Only small factions within party in power - the Conservatives - have been vocally in favour of leaving the EU.
There's pockets of the people who seem to want to leave the EU, but I suspect that's more driven by xenophobia/racism than privacy legislation.

You're looking at it backwards: established interests that hate scrutiny (mostly on "socialist" work regulations, product quality regulations etc) are driving xenophobic sentiment to engineer an EU exit that would ensure they're firmly back in the driving seat at the national level. It's similar to the US "southern strategy" that recruited religious folks to the cause of Big Business, separating them from their working-class interests. "Divide and rule" is still one of the best strategies you can employ.
