Look I understand what you're saying, but it's complicated. Obama chose to respect a tradition and he did so at the cost of allowing anti-NN people into the FCC. He could've found a republican that was pro-NN, but he didn't. You can argue about what tradition dictated, but as the president I think you have to take some responsibility for the choices being made, even if they are hard ones. Obama broke a lot of traditions and he suffered for it, especially in his first term, so I'm not saying this is a simple decision, or one that would've cost a reasonable amount of political capital, but he did have the actual, legal choice, and he did make it. This enabled Trump to select Pai as chair. So without Obama's decision Pai would not be chair either. It's ComplicatedTM.
