A few new outlets have reported that “Facebook is also looking at paying users fractions of a coin for activities such as viewing ads and interacting with content related to online shopping, in a system similar to the loyalty schemes run by retailers,” which is very similar to what the Brave browser offers via their basic attention token $BAT. I have seen no confirmation of this anywhere, only in news articles talking about Libra prior the announcement. After searching the whitepaper, I found nothing at all mentioning this and I would deem it as speculative misinformation.
