Cigna purchased Express Scripts in Mar 2018, and has profit margins of 3% to 5% over the last couple years.

If these PBMs are making lots of profits, then they are simply subsidizing losses elsewhere in the MCO. The total costs paid for insurance premium plus out of pocket costs by the end user in the US would not be affected.
PBMs are important but they should not be able to put a gun to these pharma companies heads because they control the formulary.
CVS net margin includes their retail business. You can't compare AWS's margin to Walmart's e-commerce margin.
As a customer, it does not affect me.
In the healthcare business, the flow of money is:
Individual -> MCO (insurance company) -> healthcare providers and drug manufacturers
What does it matter to the individual what portion of an MCO is earning what profit if the net profit margin of the whole MCO is 5% or less? They are obviously not left with a lot of money, their employees are not known to be lavishly compensated.
