Less so that, more in that they like to shield the heroes/villains who benefit them from any potential harm or risk. If you were to threaten their power by, say, exposing a hero who just so happens to act in a manner that is consistently beneficial to Triple N, then they really wouldn’t be too happy.
In the way of actual power politics, Triple N’s interests shift with the public. I talked briefly about how they came to power and gain the kind of monopoly on news and media in Nickelport that they have in the present-day game. It was much in this same way- their political opinions or push for change of powered law is dependent on what benefits them the most.
If that goes with your example, of shielding heroes and villains from exposing or accountability for public property destruction then that’s the position they’d appear to take. If the public was, as it was during their time of rise, oriented more towards pushing for better regulation of powers and heroes, then that’s the kind of wave that Triple N will ride (and has, as was aforementioned).
The goals of Triple N are almost entirely internally-focused. Which is… a little ironic considering their whole goal is external communication of current events (or supposed goal, at least).
As for the current state of Triple N’s politics, it’s definitely oriented more towards looser rules and regulations. But that’s mostly because they want The Rust to become more popular, and by publishing a paper (albeit secretly) that directly goes against that stated goal, they create controversy, and by creating controversy, they attract more attention- and therein more money.
So, frankly, they might be a bit happier if you went with a stronger opinion of exposing all heroes and keeping them accountable for the damage they cause… So long as you don’t go too far. (And, again, so long as it continues to benefit them.)
Plus it means they can reach into both markets- people who want heroes and villains to be held to a higher standard, and those comfortable with how things are currently.
