With this logic, one should pay Google for making purchases in their browser or Netflix should pay e.g. Samsung a fee, as users consume content on their devices. Truly ridiculous.
I actually see it as the reverse. Valve might be going for the whole pie and want to carve out a niche for their Steam Box. Inviting Apple to the party might detract from that effort. Or at the very least distract from their main focus.
They don't need Apple for that. People who game already game elsewhere. Steam on Apple feels pointless. I wouldn't be surprised, if Valve will go for smartphones with their own at some point
Building a "classic" search engine is a very fun project to go through.
