This is exactly why I don't put 100% trust in these apps that claim e2e encryption. It's trivial to update the app and destroy the contract if the company is willing and cooperating. You need hardware based security to make it truly impossible, like the case of unlocking and iPhone, although I honestly don't know how hardware based security could be leveraged for chat. Maybe in a similar way to how DRM works where the CPU never has access to the data and something else is drawing the pixels on the screen?
