I do think that it was a mistake to use the word "all" and imply that there are absolutely no bugs in FoundationDB. However, FoundationDB is truly known as having advanced the state of the art for testing practices: https://apple.github.io/foundationdb/testing.html.
So in normal cases this would reek of someone being arrogant / overconfident, but here they really have gotten very close to zero bugs.
