Does Google's YouTube group host a line of communication between its product managers and content producers? Is there a service agreement between Google and its content producers around features and site behavior that will impact viewers and paychecks?

If not, then content producers are simply in a bad long-term position and they need to start looking for leverage against it, whether it's taking their subscribers elsewhere or getting a seat at Google's table so website and mobile app updates don't start mucking with subscribers getting their content to users.

OTOH, as a user, I don't want to be inundated with notifications and especially begging notifications if I unsubscribe to someone.
