The principal values of things like the Jepsen reports is to the community of potential users/purchasers.

I agree with GP, that vendors should be somehow required or very strongly encouraged to participate in such audits. Not because they want to (as you say, most wouldn't like their dirty laundry aired thus), but because consumers deserve to know. U.S. government software groups don't like FISMA/RMF audits either, but they have to do them anyway.

I am of a contrary opinion. At some level of developer insolence, such commentary is valuable - especially if it needs to mention the core basics and foundations that keep the software world running, such as running existing Postgres test suites for a supposedly Postgres-compatible database. In the increasingly sloppified world, even such basics are being eroded - this being a proof.

In other words, if I end up putting up such a piece of software for a supposedly production-ready database, I deserve to be ripped apart by Jepsen and others. Somebody has to assert software quality; if it's not asserted internally, it must be asserted externally.

In yet another words, software development is a trust-based business. If you break it, such as by outright lying to people, then you deal with the consequences.
