I am completely unconvinced. The fact that the "average/median" income from these models is low is completely unsurprisng. We should expect that the vast majority of the income would go to the very top performers. This is not an indication that subscription doesn't work, just that it's going to end up looking like acting, music, and professional sports. Those are all real careers that have persisted for a very long time where the "average" wage is extremely low.
This article does a bad job clearly stating what the author thinks the problem is (just vaguely gesturing at average wages without explaining why that should matter), doesn't suggest an alternative at all and instead seems to snidely be sniping at non-mainstream journalists and creators.
I am deeply unimpressed.
