I think it's noteworthy that feature was pursued and implemented by Igalia, an independent open source dev house whose HQ is in Spain, and is run as a co-operative. They've built up quite a powerhouse of core browser experts.
Why co-ops? Because the profit goes back to the people who work there instead of shareholders, and they get a say in their own management. It shares control of the company between those who work there. It's a much better environment to work in vs something like Activision or EA where you're just an abused cog in the machine.
At least on paper. In reality, the smaller coops don't grow big enough and so can be resourced starved and kinda get stuck in a death spiral as people leave to pursue other alternatives while the remaining members hoard power and control for themselves and make new employees basically not full owners but minions, etc.
There's no perfect system but I'd rather take the risks of equality than work under an oppressive hierarchy.
Not everyone cares about that though. Some would rather earn the big bucks, be led by execs, and not have to worry about the rest of the business.
Igalia shares equal ownership and all new employees are expected to become owners eventually. It's been growing faster too lately. WebKit Team is hiring :)
