As another said, the goal to increase revenue is per team. The Edge team must likely find proof for how they will drive revenue in the future.
Suddenly you've got a full browser engineering team trying to figure out how to monetize a browser - tough sell. So they can't come up with anything, that's fine because a product manager is the owner of this task anyway. They propose a myriad of different ways to monetize Edge in the future:
* A "Edge Pro" subscription $10/mo where you get ad-blocking and no tracking (we'll need to block third-parties from offering this)
* A built in way to pay people online, we take a cut. Hey maybe we finance big purchases and that's a unique selling point?
* Premium apps/websites, web page authors can give access only to users with an Edge subscription and in return they get a cut of the profits.
They discuss these options as a team, and decide which one is least likely to cause backlash and is least difficult to "try out" and they land on what we're seeing here.
