Yes it's hard to stop people from speaking and intimidating. That's why I almost see an elegance in this solution: if FB and other corps don't know who is contributing which part to a bill and they only get to look at the final answer, it's harder to know who to intimidate and who to blame. In other words, it's believing that politicians are being intimidated to decide in one direction or another and trying to give them cover to make more sound decisions.

Right. Someone comes in to bribe you, you take their money, you go vote against them anyway. Then when they come to you to object, you can shrug and say it must have been someone else. There is no way to for them to verify that their bribe is having the intended effect, so they'd have to pay you on faith. And who is going to trust a politician who is accepting bribes? They could be taking them from both sides!

Precisely.

And without knowing for certain whether that person actually voted in the committee for X or added X to the bill, it also makes it hard to know whom to intimidate, whom to threaten by being primaried out, whom to defame, etc.
