It's kind of amazing that people still hit this, really. Like, if you're Facebook's lawyers, how are you not telling them "don't talk about this; anything you say or do will only promote it further"? The lawyers must _know_.
Lawyers get paid to “do something”. To wealthy people, a lawyer saying “let’s actually not do anything” seems like a “what am I paying you for then” moment.
(Perhaps it’s more accurate to say they did not think it would manifest but that’s not a fun play on words.)
They can't even control their client from lying in public.
