You are arguing on semantics. The word "transaction" in the title doesn't refer to bits and bytes transactions found in the blockchain but to the more common definition "an instance of buying or selling something". I agree that a better title would have been: "Stop saying that Bitcoin transactions have to be irreversible".

Every domain has domain terms: specialized knowledge and vocabulary.

Within payments, "transactions," "reversibility," "revocability," and "escrow" have definitions. Since BitCoin is in this space, I'd expect an article to use the domain terms from this space.

Yes, if you re-define these terms to mean something more colloquial, it may look like that. If you squint. But that doesn't make it not look amateurish.
