On Super Bowl Sunday, Remember Billions of Taxpayer Dollars Subsidize the NFL

This was technically true but not in the way that people think.

The TL;DR is that each team is a for-profit entity that pays taxes based on their income while the NFL exists to handle some administrative duties but does not draw any income of its own. All of the money is taxed as teams' income.

And it hasn't been true since 2015 anyways.
