It would also be difficult to going around telling people about the Maidens and Salem without sounding like a madman (especially Salem). Plus any of the leaders who would consider doing it like Ironwood, not only has the getting people to believe him issue, but also convincing the other Kingdom heads to go against the in-universe presumed dead Ozpin's wishes and convince their citizens as well.

Doing all that with tensions between the kingdoms and as Ark mentioned, a global blackout. Shit's difficult and there are other priorities on the table anyway.
