Economy of scale is very much a thing in physical distribution (so smaller board games have to set aside significantly higher percentages to manufacturing, logistics and marketing), and I lack the business knowledge to know how this does or does not translates to digital distribution.
In other words I cannot judge that, but I have two indicators to suggest it might be a thing:
Physical distribution mirrors it.
Sweeney is an absolutely untrustworthy source, and him so vehemently poking at it suggests it’s a false narrative.
(Plus let’s not forget that Sweeney would take a 105% cut if he could get away with, he himself is a money-greedy bastard)
