Other fields use the words profit, not just accountants. Economists and philosophers, at the very least, have a claim to it too, and they do not in any way conflate the meaning with the accounting definition. Indeed, we would argue that the accounting definition is the one that is conflated with the thing we actually care about (which is why the phrase "paper profits" even exists).

And its also quite clear he didn't "conflate" the meaning, but used it exactly as intended.

Most people, I'm assuming, can quite clearly see that he captures the idea that surplus value/revenue, of which the resulting wages are a non-deterministic and variable part to some degree. That upper management of the firm take a percentage of this slice of the pie, whilst lower down labour also gets a slice, and that the notional "social justification" for why upper-management gets a greater slice is being white-anted away as the lower downs are supposed to take on their responsibilities without commensurate compensation.
