The world of networks once was segmented into several, with the Internet being the odd network out there. The benefit of having a single network is being able to share everywhere and nearly instantly, the same as the benefit of open sources or sharing in scientific research. (Teller: "Secrecy, once accepted, becomes an addiction." and "Secrecy in science does not work. Withholding information does more damage to us than to our competitors.") Moreover, the ills of the present Internet infrastructure are arguably attributable to its application in commerce and the highly indirect way in which its infrastructure is constructed and how it is funded. If, in fact, components were implemented in full compliance with extant RFCs, many of these exposures would not exist. Indeed, inconsistent enforcement of standard best practice lies at the root of exposure at many companies. Why don't they enforce? Because they have, as yet, no financial incentive to apply the resources these upgrades demand. Do they are about the health and existence of the Internet? No. They are pure opportunists, as are many corporations.
