Whatsapp, a division of Mark Zuckerberg's Facebook, has banned numerous users in Brazil including Presidential frontrunner Jair Bolsonaro's son in an effort to reduce the number of messages promoting Bolsonaro's campaign on Zuckerberg's US based platform (archived). With the presidential election less than a week away, this is exactly Facebook meddling in a foreign election to favor one candidate over the other.

Considering Facebook's ongoing cooperation with the US Government, it would make all of the sense in the world for Brazil's outgoing Temer administration to strike Facebook and the United States with sanctions.
