I don't think the parent was suggesting there be a single trusted third party.

This is overall great. QLDB is necessary for a lot of things, and it will be useful for a lot of the stupid 'blockchain' projects to be displaced by a better technical solution.
Now cryptocurrencies and blockchains are exactly what they are: a decentralized version of this. I believe that decentralization has some use cases that are extremely important. Now it can stand on its own, without being conflated with verifiable ledgers.
Using a private blockchain has the same issue of trusting a third party. As soon as someone has control of who can write to the ledger, you need to trust them, period.
A lot of people would assert that "private blockchain" is an oxymoron. The semantics have not resolved yet.
I expect that they will resolve to exclude such things.
Well AWS is already the trusted third party for so much stuff. What's another db ?
What does an industry with thousands of different major players have to gain by coming together to give a single company a monopoly over their entire industry? And in fact, one of the biggest strengths of blockchain is that it provides a viable alternative to monopolies for various industries.
