Big successful launch, hype for the product lead, product lead moves on, product goes to shit. Another classic for the Google graveyard.
I do think it is fair to say they had been caught off guard by the success of the program and are trying to catch up. Maybe this is just a bit of drift as they are figuring it all out? Or maybe I am too charitable.
Doesn't matter how talented the team is, that is a massive red flag as not even six months have passed since the launch.
