It's as simple as that. NijiEN is made for Nijisanji to build an English fanbase of their own and Petra is failing at that. That's why she gets "hate" at the end of the day, not because she speaks Japanese, not because she only does zatsudans, not because she's a "zhang," but because she fails to do the same job all 5 other members of NijiEN are attempting to do.
