I'm sure Apple is contributing significantly to many of those shows' budgets and helping them all reach similar quality bars, but Apple is also certainly benefiting from spreading that budget across multiple studios and not putting all their risk in (micro-)managing their own studio. Whereas a lot of the "streamer X has gone downhill" seems to be directly related to being able to source projects only from sibliing studios creating very simple monocultures of every project feeling the same and risking that bad or unlucky projects tainting other projects in that monoculture stew.
