I hope they mean the project is precious but the formal organisation that funds the project isn't. Like Firefox and Mozilla.

Before LLMs, Wikipedia was the greatest source of misinformation in all of human history. It is at best good for satiating an idle curiosity with some plausible-sounding fun facts to amuse oneself with without care for whether they're really true or not, but so many people rely on it for so much more, and I have little doubt it causes more harm than good. Real encyclopedias with professional standards exist.
