Correct.

Knowledge consists of, roughly speaking, thoughts.

(a "justified true belief" - per https://plato.stanford.edu/entries/knowledge-analysis/ - is a kind of thought)

The "thinking" part of a "thinking being" - that also consists of thoughts.

If your knowledges are someone's property, you are someone's property.

A society where all knowledge is proprietary, is a society of ubiquitous slavery.

Doesn't matter.
