End to end matters, who has the key; you or the provider. And Google could still read your messages before they are encrypted.

You have the key, not the provider. They are explicit about this in the implementation.
They can only read the messages before encryption if they are backdooring all android phones in an act of global sabotage. Pretty high consequences for soke low stakes data.
