You make a valid moral point here.
However I would comment that to all intents and purposes Usmanov/ Moshiri have invested money into the club rather than extracted .
If this consortium takes money out of the club, and given the close association of Bannon to one of the members , it is not beyond the bounds of possibility that some of that money could find its way into the hands of Bannon.
Even the slightest possibility that a smallest portion of the money from Everton could indirectly find its way via the obnoxious Bannon into the hands of the multitude of extreme right wing groups he supports /sponsors across the USA and Europe (including Britain) is very disconcerting.
