Respectfully: there was no way you could have written that post to be "neutral". Regardless of your phrasing, it was going to be "don't believe this poor [in a literal sense] guy, do believe multinational enterprise freelancer dot com."

A "neutral" attempt to "add context" with regards to such a power dynamic is always always always going to be "don't listen to the weaker party." Always. Because such a thing always and, frankly, I expect was designed to delegitimize the claim.
