Usually refusing to share information or API is a business choice. Besides, once you have a closed group, you just have signed transactions ("permissioned blockchain"), and can (must) ditch proof-of-waste. So it barely resembles what people normally think of as blockchain and starts to look more like signed git commits.

It's a worse API. In that situation, you have trusted parties. You don't need a blockchain, and the absolutely crippling tradeoffs it brings with it.

Sometimes the “API” in these circumstances is CSV files sent by FTP nightly over private fiber links.
When all parties are trusted there aren’t necessarily any crippling tradeoffs, you get mathematically provable ledgers with no need for a central trusted clearinghouse.
One quiet place where blockchain makes sense is shared ledgers between large financial institutions, JPMorgan for example is working a lot on this. It's not about privacy or usurping the social order or whatever imaginative solution to all of society's problems that gets attached to so many other things... it's just a better API between institutions for transferring ownership between themselves, which is a frequent and often awkward (and ancient) tech.
With blockchain you don't need a third party, with big institutions "theft" doesn't make sense. If there is an error and a transaction needs to be reversed it's in everybody's interest to do so and expected to happen from time to time and likely a built in feature.
Simplifying way back end transactions between banks is pretty nice... for banks, but pretty uninteresting to most people because it's just about settling daily balances between institutions and the like which is really boring.
