I think it goes back to the quantity thing. With more cis performers it becomes easier to find alternatives who'll be consistent. Whereas the number of actually feminine trans performers who'll be consistent will naturally be higher.
Hell despite there being less trans performers we still got RayRay*, KianaVi, RoseMarieJackson*, Lavaltl*, Aniolero*, MyTSGirlfriend, SummertimeJames, and more who make consistent good content with no scammy practices.
When I think of the break takers I can only think of like Sara Salazar, Melody Monae, and Rei Emi* though again there's prob, my bad if i'm just ignorant to the rest.
