It's probably fine for most people when eaten in reasonable quantities, but it's good to know that it can cause problems for some. Then there's the whole issue of the rebranding to "white tuna" from "escolar" or "oil fish", and further confusion when it's not even escolar that you're getting, but some other oily fish. My favorite fish rebranding is still "Chilean sea bass" instead of "Patagonian tooth-fish".
I'm not sold on the downsides of escolar. I think it's pretty delicious, actually. There's not a consensus from my research (of about 5 minutes).
