I wish the Selenium (and Appium) projects would get mentioned in these kinds of conversations more. When starting these projects, I was very intentional that we set things up to not screw over users down the road and that we set things up so that multiple commercial vendors running SaaS services (not just my own: Sauce Labs and Tapster) could succeed, too. And, yet, the success of the Selenium ecosystem to thrive for 19(!?) years is basically invisible in most discussions about open source funding and incentives.
