The pre approval of tweets seems worse than the total ban. Initially, I dont really see a social media ban as racist but if they are picking and choosing what kids get to say on an individual basis, that could get really messy. I wouldn't agree with a blanket ban but I can get the logic behind it. The no hats, earrings etc...would probably not seem terrible on its own either but when you start piling all of this together, it all seems really authoritarian. It's really easy to see how players felt like they were forced to conform, especially players who came from places that are much different culturally than IC.
At some point, you have to start to think that even if KF sticks around, the major changes to the program might be too much for him to maintain success. A total rebuild of the program culture is obviously needed. I'd be leery the guy who helped create that culture can be the one who can change that culture.
