I am also disappointed, but not because I have presupposed the answer. I am genuinely curious as to whether Gilead will say "All right, drugs were fun but we're gonna do mobile gaming now," or whether they are making enough revenue from other markets and perhaps other drugs that they'll continue to discover and develop drugs like Sovaldi. I don't think the answer is obvious to someone (like me) who hasn't been paying close attention to the profitability of drug development, so I would have appreciated

In particular, while I can see grassroots protestors not thinking about the long term, I vaguely assume that Médecins Sans Frontières knows what they're doing, and wouldn't have been backing this strongly if they didn't think it was also a long-term good strategy. But I definitely would have appreciated more discussion of that point, since I don't put much stock in my own vague assumptions.
