The main problem I find with the townsponies shutting out the CMC in Ponyville Confidential is that, because of the events of the previous scene (them being blackmailed when they tried to quit), it came across less as “you deserve this” and more as “the world is against you and not letting you repent”. If the blackmailing was removed, and just turned into Diamond Tiara talking the CMC into continuing because they could get their marks, the isolation scene would feel significantly more deserved.
 
I never understood why the Main Six get angry at the CMC when their secrets are complete harmless. Probably the episode show us the problem about our society has when people overreact from the most harmless thing like how people complain about cameras in public areas and call it invasion of “privacy” when it is not an invasion of privacy at all.
 
What made me mad was that AppleJack and Big Mac turn their backs on their own sister because they both choose to read those newspaper articles about them. But instead of throwing it in the trash, they turn cold and angry from reading it and give Applebloom the cold shoulder.
 
So, I have my OC, Devon Darkhooves to come to Applebloom’s rescue by telling off her brother for yelling at her, and her friends. And Big Mac knows better then to mess with my OC’s when his poison tipped tail is involved.
