I'm not saying I condone what happened. I just see people claiming corruption, and I personally doubt that. I think its more along the form of "lets remove these reviews for now and analyze them tomorrow"
Corruption is a tricky subject. Pawns of a dictatorship, a mafia or any hierarchical corrupt structure... They might not be aware of what's actually going on but that doesn't change the fact that the structure is corrupt. Whatever caused this, Google's guidelines, its business practices, its investor relations, is corrupt.
