The downside is that would still make it harder than necessary to access and leave some people out. The upside is that it's not that much of change from their existing model. I'm sure there would also be concerns about database dumps being shared publicly, although Anna's Archive has already released their entire database, and I suspect most people who would pay for formal access wouldn't use an authorized copy. Ultimately, I suspect OCLC would still be resistant to this change, as it would feel like a huge shift, even if I'm not sure it would change much from their perspective.

I know a bit about Henriette Avram and her work at LoC developing MARC, but it of course makes sense that other libraries were thinking along similar lines at the time.
Libraries (often publicly funded) produce all the work, OCLC claims ownership of the results of that work, Libraries pay to get it back (but they do get a discount if they contribute).
The only reason OCLC continues to exist is because libraries don't have the support or resources to fight them. It's very similar to the Elsevier issue in academic publishing, but OCLC does a better job with PR.
OCLC is exactly what happens when the libraries want to avoid another EBSCOhost or Proquest situation with ILL.
Here's an explanation from their footer: "Although Dewey invented his system in 1876, recent editions of his system are in copyright. LibraryThing's Melvil Decimal System is based on the classification work of libraries around the world, whose assignments are not copyrightable. The "schedules" (the words that describe the numbers) come from a pre-copyright edition of his system, John Mark Ockerbloom's Free Decimal System, and member contributions."
It came out when the Library Hotel in NYC used some of their notation as their room numbers and were sued. Everyone was WTF?
Back when OCLC was founded, the idea that people would want to have a copy of a card catalog for personal use was laughable, so I'm sympathetic to the people that set up their funding model. It's far cheaper for a library to subscribe to Worldcat than to hire a team to maintain such a database, so it created a win-win situation.
However, keeping the world's books' metadata a secret (and leaving control in the hands of a monopoly) is an anachronism.
It's well past the time when someone (such as an international coalition of Libraries of Congress) should figure out how to sustainably fund OCLC while also releasing their work into the public domain.
