If they would focus on outing personal data of Senators, Congressmen, etc, that's a fairly direct path to action. I imagine there's some curious location data there.
Other cases -- Harvey Weinstein and Jeffrey Epstein are both exemplars -- show that widely-known incriminating information can remain in broad circulation for decades without harm. It's somewhat less the information itself than the political and power balances surrounding it, which precipitate the final fall.
In the film Das Leben den Anderen (The Lives of Others), a fictional-but-highly-realistic account of the East German surveillance state, among the most poignant aspects was not the brutal suppression of political opposition, but the corruption and co-option of the surveillance system for personal gain and enjoyment -- the East German official coercing Christa-Maria (played by Martina Gedeck) into an affair that was effectively rape.
I've pointed out that Herbert Simon's defence of a data-intensive world on the grounds that the Nazis accomplished their atrocities without the benefit of automated data processing has since proven quite false: IBM were a willing and active enabler.

Data and information change behaviours in subtle ways. I'm strongly convinced of this, though I wouldn't be able to define or describe all the ways.
