I know the point here is not to call out FB in useless arguments, but one thing I think is maybe fair to contribute is that FB groups [1] and pages have come to be the really useful parts of the ecosystem (notwithstanding Whatsapp). This also poses a problem that other sites (especially late 90's sites) have had, which is that they can lose their data at any time.
