And? Why would that be my problem? I'm in the business of selling HIV cures, not HIV treatments.

If I get to undercut your entire "HIV treatment" business AND line my pockets with your entire market share, then, good for me, bad for you. Sucks to suck. Should have cured HIV first if you didn't want me to do it.

There are many, many, many examples of "newer and better treatment X kills the market share of older and worse treatment Y" in the history of healthcare. Your conspiracy theory model predicts this never happening.
