It's not a protest, it's a bunch of wankers with delusions of grandeur making yet another embarrassing attempt at trying to stay relevant. Woodward is Glazers' yesman, they won't make any moves against him as they trust him, due to his obvious financial/commercial success, which translates into money, the only thing they'll care about.
It's down to Woodward to ask for help in footballing matters, seeing how things how I cannot see him giving up any soon, he'll do everything he can to prove that he can handle it, even if he cannot. The 'United is set to appoint a DOF' is a cheap talk, at best Woodward will appoint somebody who'll be his yesman because he won't want to give up a good chunk of power that he currently possesses.
