Those free markets really did benefit the people and the country. And they were compatible with taxes and tariffs.
Bezos is using the corrupted modern meaning, “free to charge economic rent” because he wants amazon to capture a greater share of global economic activity
Usage varies, but most commonly "free market" refers to an economy that is not centrally planned. All economies have at least some level of central planning, as well as at least some degree of economic freedom for participants, so the term is somewhat like the usage of "right" and "left" in politics, where it just indicates which side of a center line someone or something falls. Any market on the free-er side of the "center" can be described as a "free market."
So it has basically just become an antonym of socialism. I don't think it necessarily implies anything about a tacit approval of rent seeking in the economy.

But now it's a bad deal:

and wants to impose 25% tariffs on MX and CA—in violation of the free trade deal that he signed.
He's trying to get them to stop promoting socialism/statism.
