People spread misinformation on Facebook. Arguably, it's not Facebook's responsibility to fact-check anything.
Facebook is not a publishing house (at least not the Facebook social media platform as such) and mandating that they fact check and curate their ads and content is tricky business. It requires a legal definition of truth, which is a matter complex enough to justify the existence of the whole judiciary system.
Expecting that a condensation of such a system be applied to the publishing of information on any platform is wishful thinking at best.
