Just the US or to all governments?
Will this transparency be available to the Russians? Saudi Arabians? Egyptians? Nigerians? Brits? French? Iranians?
Even though all nations interfere in everyone's business,the undisputed number one interferer in others countries business is the United States government.
Anything short of of making these tools available to everyone would position Facebook as an agent/agency of the US Government.

As an aside, the Russia brouhaha is a ridiculous sideshow led by people who are yet to come to terms of defeat. If a Less than a million dollars of Facebook ads shown to a few thousand people can determine who becomes president in the US, then there is a much bigger problem.
But we all know that's not the case.
