No, the BBC will not comment as they will expect it to fade away before next weeks show and people will still watch.
If they thought for one second that something really bad would happen, people stopped watching so their viewing figures went down, or people stopped voting by phone so no money coming in there, then yes they might make a half hearted mention of it on ITT. But right now they will batten down the hatches and wait for the storm to blow itself out.
Lets be honest, on ITT Zoe only reads out tweets and emails from viewers that are up beat about the people she is interviewing. So yes, she 'may' mention the social media going crazy about Jamelia leaving when she interviews her and Tristan, but she most certainly will no go into details, and it certainly will not be mentioned when Peter is on the show.
Mind you, XFactor bosses must be rubbing their hands in glee right now, lol.
