When talking about investments, "profit" is generally a synonym for "net income." Of course, many people may disagree on which specific income measure should really be used to represent the general concept of profit, but there are pretty good arguments for net income being that value. Investopedia [0] has an article that discusses the difference; Motley Fool [1] argues it's the same.

If we want to say that positive cash flow is a better measure here, you can argue that, but that wasn't the claim made in the comment I replied to.
