I'd say it's worse than this. The Americans UHC (and CEO) harmed were all paying customers who were denied coverage for claims. Apparently (quick Google search), UHC denies ~30% of claims, while the industry average is 16% [0]. Their net income has also doubled from $11b in 2018 to $22b in 2024 [1].
