I see you didn't read the article.

For one of the organisations making money:

AFLDS referred over 255,000 people to speak with physicians in order to get Covid-19 treatments. Of those people, 72,000 paid $90 for phone consultations, and many of those had follow-up consultations costing $59.99 each. The hacked data from Cadence Health does not include payment data itself, but doing the math, in just that two-month period, patients appear to have paid more than $6.7 million for phone consultations alone.

So you see that the money was charged for consultations, not by Merck, who don't recommend it for covid.
