You can't just make up a series of facts and then claim that you've shown something not made up

I wasn't positive what I'd think of Going Infinite going in -- Lewis is obviously a great writer, but I've disliked more of his books than I've liked. I ended up reading it twice. It was interesting and somewhat fresh.

I think this review takes the approach that could be seen coming from Lewis's surprising take on SBF -- to act like Lewis was even more sympathetic than he was. Though the big stuff is a fair criticism (Lewis thinks SBF is more dumb than conniving), a lot of the reporting on SBF's perspective doesn't seem fair to take as an endorsement of the perspective, and I think that Lewis's take, even when likely wrong, is often way more interesting than pointing out that SBF is indeed a thoughtless asshole, etc.

That is not what profits mean. Your expenses count. Your payroll counts. This is absurd.

This seems like a normal use of profits for trading profits. It's, as you point out, not the firm's profit.
