Do you think you would be satisfied if they were the only game in town?
UPMC might be the most profitable "nonprofits" ever. And they have multiple times used their nonprofit status to take market share from for profit providers. The are a near monopoly and pushing to drive any competitor out of business.
Give me some competition, and allow me to decide.
I remember making a similar argument years ago about Microsoft.
But "Conservatives" stood behind Bill Gates and blamed the mean, nasty Antitrust Division for picking on him.
UPMC has given me decent service. I repeat - I'm satisfied with them.
