I think you will be surprised how decisions are made in Big Tech, especially Google. If they are truly metric driven, it will be really hard to explain why they would end up with so many different messengers, and continuously discontinue some and churn out new ones and repeat. Even if they claimed to be, I am afraid they way they read the data is very different than we understand the data, after all, data is just a way to win the argument, the decision need to be made by human.
