3rd parties should not get the chance to weigh in on journalist's reporting quality. Reporters should be able to succeed or fail on their own. What are you, working for or on behalf of B. of A.?
I happen to have a bank of america/ML account because I am a software engineer who got stock options that vested. Like probably a lot of readers of ycombinator. So I am going to write them a letter complaining about this action. I'm about to close my account there. This is one way to attempt to make an impact. Also I recommend complaining about the third party company that apparently sent the dmca. Those dmca takedowns seems to experience little or no negative effects when they make mistakes. This is hard to change through legal means, but it can be changed through public pressure on those companies.
