I don't like this arc. First, there was the "How could Okabe bow down to the company, hide her AKB past and go by a stage name?" outcry by Minori (despite the fact he's also hiding his identity to succeed in the company), to the point he lambasts Okabe for being fake and lacking sincerity. Of course, no mention or criticism is given to the far more draconian measures AKB48 imposes on their idols to construct an equally fake and insincere public image.
And now this "Yuuko-san never forgave you for graduating" or "You've betrayed this many people"... Seriously, more than praise for AKB48, it makes them look like a cult. I understand that this manga is there to promote AKB48, so it's not as if they're going to bite the hand that feeds them. But their insistence in accusing Okabe of things AKB48 does all the time to make her play the villain of the story reeks of hypocrisy.
It's even more jarring when I remember Okabe's appearance in ch. 202. While everyone else was incensed, Minori was understanding. And Okabe was given the chance to explain herself with the hermit crab metaphor: AKB48 is not the center of the world, and if you want to grow on your own, sooner or later you'll have to leave it (all of them will graduate, after all). That subtle and open-minded self-awareness seems to be forgotten in favor of painting Okabe as a traitor for selling her soul to the American Devils.
