When I said "subsidizing someone's business" I referred to throwing public money at a sector as a whole (anyone can enter it, most people won't) not a particular person (esp not Alex, obv).
To be fair, I do not think HBD Stabilizer prefers any particular trader over another - it just places a big order anyone can pick up (I may be wrong as I guess it would be technically possible to deal someone the private info so that they can snipe it).
I know no proposal is 100% "what we want" so I made sure to explain why this particular subsidy seems sub-par to me.
