First of all, whether they are shameless or not doesn't really matter. If sexually explicit pictures of a politician end up on the internet, his reputation takes damage. It's beyond his control. Plenty of politicians are willing to go to great lengths to avoid this. So what does it matter if he's shameless or not?
Second of all, politicians and other powerful people might have something to hide that isn't just embarrassing but is also illegal. It's certainly not beyond the capabilities of the NSA to target powerful people that oppose the NSA while ignoring those that support them.
For example, in the news you might read about a CEO that gets convicted of insider trading. Nothing to worry about, right? Well, what if the NSA purposefully targeted him because they don't like whatever it is he's doing? Using parallel construction, it wouldn't even have links to the NSA.
