Of course, anyone can do a google search and find some opinion pieces confirming their world view, that doesn't make it true.
The post article in particular just looks at the total revenue and essentially says "look how big it is compared to other countries, we must be subsidizing them". But this just justifies the extreme profit-seeking already in the sector, it's not an argument that it's necessary for innovation.
Even your own source [1] contradicts the idea that high costs are inevitably caused by this subsidization:
> Why doesn’t competition bring U.S. health-care prices down? The answer: America’s stagnant third-party payment system allows hospitals and doctors to avoid competing on price.
By removing the for-profit system, you would actually be removing rampant rent-seeking on something that should be a human right.
> Imagine if the price of insulin, almost completely funded by US citizens paying absurd prices, went up to its US price.
A very strange example to select, considering it was first discovered by Canadians and the patent was later sold for $1. US citizens are certainly not "subsidizing" insulin elsewhere.
