I think there are important considerations to keep in mind.
First and foremost, Valve is not a public company. I don’t know if it has investors, but it is not driven by profits like many typical public companies are. These companies tend to allow themselves longer investments without any clear visibility of immediate profits. They also do things for the greater good, even though it does not bring profits.
But also, I think the whole of valve is a set of gamers and people who genuinely care about the gaming business and making great products. I think they all share Gabe’s values and goals. It’s not like Gabe is the only one holding everything together or else it would instantly crash into the profit driven company it could be.
Both of these scenarios keep me hopeful that this is a longer lasting stance and doesn’t hinge on just one person. It’s not a proof it will never be a typical profit company but these are barriers which are not typically present. Let’s hope for the best and keep rewarding them for their contributions to gaming, open source and for their good actions.
