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].
And just to be clear for those not living in the USA, the people being denied coverage by UHC are the same people paying health insurance premiums to UHC in order to have health insurance coverage.
