I mean it's clear that their brand has just become bigger than only watching VCT. Which is fair because compared to other games like CS, watchpartying VCT is not a year-round schedule, there's long breaks in between that have to be filled with something.
So from a financial perspective, I would guess that their audience is so big that it's more about retaining viewership and fans with new/exciting content than trying to recruit new fans into the ValComp scene.
