But neither does profit motive. Is facebook maximizing the benefit of their users?
It’s more like maximizing benefits to the minimum amount of people at the expense of the maximum number of people.
Sure it does. Developing a cure for 100 people will generated far less profits than a cure for 100,000 people.
It's why you see cars get better every year and constant attempts to appeal to the widest customer base possible. (That didn't happen with Soviet built cars, which tended to never improve.)
As for advertising platforms, the customers are the advertisers.
But in the first paragraph, the side effect is that developing a not-quite-cure treatment for 50,000 people is more profitable than both the others.
As for the last paragraph, this is perhaps the essence of the problem. The motive is profit, so we only care about the advertisers. But the users are real people too, and they are getting screwed.
