They simply want the assurances given in the document, that access be reasonably-priced and non-discriminatory. Want a good example? DES and Ethernet were patented. (The DES patents have since expired, and carried no license fee in any event. Technically, though, I think one needed a license, and I've heard rumors (that I never confirmed) that one could get a license if and only if one agreed to use only the four standard modes of operation.) Yes, it surprised me, too, when I learned that proprietary technologies could be blessed by ANSI and IEEE. Then I thought a bit more. These are organizations that serve *businesses*, not universities. Businesses, in general, do not object to paying reasonable fees for services rendered; after all, they themselves charge for similar services. Now, they may disagree as to the validity of particular patents, or even about the principle behind certain patents (though businesses rarely have principles, per se, as opposed to bottom lines), but paying for designs and specifications is quite common in the business world. Academe is different, of course; there, free software, educational discounts, etc., are the norm. Even the IAB has blessed RSA for PEM, for the simple reason that no alternative seemed feasible. And yes, a reasonable license fee is being charged, though a substantial portion of it is for the certification hierarchy, rather than for patent royalties.
