I think you might be right. I usually think of theories in this sense: https://en.wikipedia.org/wiki/Theory_(mathematical_logic) https://en.wikipedia.org/wiki/Theory_(mathematical_logic) And similar epistomological variants. But a bit of googling suggests that a distinction is made between a generally accepted and well tested theory, and one that's in the early stages and not well tested (which is termed a hypothesis as you note). In any case, this is just disputing definitions, rather than testable propositions about the underlying reality.
