Valve is not well meaning. No large for-profit company is ever well-meaning. It’s merely the case that Valve’s best interest happens to align with those of the consumer, and they have decided that their business model is going to be to win over consumers’ loyalty through goodwill rather than milking them for every penny they can get. And they are very successful at this, seeing that there has still not arisen any serious competitor to Steam. That’s entirely because consumers are loyal to the platform. Valve provides a good service, consumers reward them with loyalty. It’s not friendship, but it’s symbiotic, which is as close as you can get to friendship in the harsh world of business.
