No they’re talking about general reduction of bed rest after birth, not that c sections have shorter hospital stays. It is also describing a process that originated in the 19th century, not a recent phenomenon.

That sentence is wrong. Women stay longer in the hospital after a c-section. You are right to question the article if that is what it says.

The fact that there is a profit motive behind the overuse of c-sections is a settled issue. There is. There are investigations, there are studies, and there are metaanalyses of those studies. C-sections are a relatively easy procedure with predictable results that minimise litigation risk. It is frankly absurd how high the incentive is for a hospital to perform one.
I can’t comment on your baby in particular. I don’t know the relevant facts and it would be wildly unethical to comment on it as a result. But with regards to whether there is a financial motive to perform c-sections in general the science is in.
