I think the wording of your options is a bit misleading. It’s valuable to publish your criticism of any topic that’s taking up non-trivial EA resources, regardless of its true worth as a topic—otherwise we might be wasting bednets money. The important question is whether or not infinite ethics fits this category (I’m unsure, but my best guess is no right now and maybe yes in a few years). Whether or not something is a “serious problem” or “deserves criticism”, at least for me, seems to point to a substantively different claim. More like, “I agree/disagree with the people who think infinite ethics is a valuable research field”. That’s not the relevant question.
