From the Wikipedia page:

In the late 20th century, many Americans with classical liberal beliefs began to describe themselves as libertarians.

I was alluding to that, but I appreciate the added clarity.

“Classic” libertarians were anarchists, communists, and socialists and the term was co-opted and its meaning shifted by capitalists and liberals. That’s my TL;DR.

https://en.wikipedia.org/wiki/Libertarianism#Definitions

Although libertarianism originated as a form of anarchist or left-wing politics,[27] since the development in the mid-20th century of modern libertarianism in the United States caused it to be commonly associated with right-wing politics, several authors and political scientists have used two or more categorizations[9][10][28] to distinguish libertarian views on the nature of property and capital, usually along left–right or socialist–capitalist lines.[11]
