The "what" is that there is no moral difference between the Me Too movement's abhorrence of a boss who demands sex in exchange for advancement and a subordinate who offers sex in exchange for advancement.

There is a moral difference.

One is between conscenting adults, the other is a demand from a boss.

You are correct that third parties are disadvantaged in both cases.

The offer from either side is reprehensible because it is made for a corrupt motive.
