One thing that HP does for VMS is ship all the runtime libraries for all their compilers (even the weird ones like BLISS and PROLOG) as part of the base OS. That way ISV vendors (or the base OS vendor) don't have this kind of problem. Paying to create, free to use always seemed like a good compromise to me.
