This is a valid criticism in general, but I think in this case, user was asking for instruction. "You say this is strange, but this other simple explanation would explain it to my knowledge. Why is this different?" is intended in this case to be "Instruct me so that I may detect my error and update" rather than "Have you considered X?"
Since I believe you are also asking genuinely, I will attempt to disambiguate the two cases with illustrations:
1. OP states the question as "Could this be the same?". This expresses uncertainty of the form "Is this possible?" and "Are these simpler explanations still on the table?"
2. OP may have stated the question as "Did they consider X?". I think this moves closer to the idiot advice that is often of the form "Did they consider correlation is not causation?" etc. etc.
3. OP may have stated opinion directly: "They did not consider X". In this case, lacking knowledge of OP expertise, you may safely conclude that this is a statement from an armchair expert.
Of course there are an infinitude of statements and responses. But hopefully these 3 examples will help.
