> The $1.1 billion figure is for Truvada total, not for PrEP specifically. It’s perhaps notable that Gilead chose not to break that down, given that the original claim they were responding to was about PrEP specifically.

And even then it's a dishonest claim. Half of that $1.1 billion is the amount of money they paid to acquire another biotech company in a firesale. It's beyond disingenuous for them to claim all of that towards the amount they spent developing Truvada, since they received way more assets in that sale than just the patent for one drug.
