wpegg: Your argument could only hold water if Steam were pursuing an Epic Games like policy of exclusive releases. I looked, though only briefly, but could find no evidence at all that steam have required a publisher to not release on anything but Steam. I suspect the reason for this is that they're one step ahead of you on the whole competition law thing.
Steam 100% does offer inducements to exclusivity, they just don't directly pay publishers. Steamworks is 100% an 'in kind' inducement to exclusivity as it's a suite of production aids which reduce cost- and that 'just happen' to be exclusive to their own ecosystem. Indeed I included one example in the post you quoted- Workshop. Only works in Steam, replaces something that is platform agnostic and works for everyone (nexus) and if you use it it takes extra work to decouple it for a non steam game version, but hey- steam integration! What is one of the most common excuses for not having a steam version? "We used steamworks to save time and money, and it's too much work to or we cannot unpick it for a non steam version". That is not an accident, from Valve's POV that is 100% Working As Designed and is the entire point of offering Steamworks.
They can also threaten to throw pubs/ devs off the platform (via so the called 'EA clause', which was never targeted at EA/ Origin, which is too big) or make it impossible to launch actual competing storefronts (as opposed to glorified key resellers), as they allegedly did to Paradox when they were going to launch Connect as a competitor. That's an existential threat to many, given Steam's market dominance.
There is far more to exclusivity inducement than just getting money directly. It was extremely rare for MS to directly offer money (so far as I am aware it never happened, it was always in kind inducements) when it was crippling WordPerfect or 1-2-3 or trying to embiggen IE; they offered an integrated experience, free training, direct OS support from the vendor, scripts and bundled other software to make them attractive- and hobbled the competitors by not giving them access to OS developments that their own team got. Most you might get as inducement was a discount for bulk buying licenses and a bonus for exclusiveness, no direct payments. All those integrations, of course, didn't work with WP or 1-2-3 even when they probably could have. So, you can use Office and get all its benefits. And that is 100% where Gabe learned his strategy for Steam.
