>>Or perhaps it is rather that they simply found the offer offensive.
I guess it is difficult to know without being aware of the underlying politics and relationships- or of Brazil's existing investment in the prevention campaign that may make $40m with strings attached seem more trouble than it is worth.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
