It is not a sin of commission Mongo is accused of, but a sin of omission. MongoDB out of the box is configured to be fast-but-unsafe. Postgres and other databases out of the box are configured to be safe-even-if-slower. A benchmark which doesn't spend the time to configure both systems equivalently (i.e. most community benchmarks) will therefore show MongoDB as the faster system. The policy of not publishing/commenting on benchmarks simply allows misleading benchmarks to be created and to stand. It's a self-serving policy.

Mongo has repeatedly chosen defaults for their database which make naive benchmarks look better, at the expense of production safety. You seem to be willing to attribute that to Mongo's incompetence. Proverbs are on your side, but it sure ties in nicely with the "leave the benchmarks to the community" policy.
