Because loads of people work from home these days and have about 40 hours a week worth of content to fill, before even considering time spent at the gym, walking etc. They aren’t limited to 2 hours of content per week.
I’d also always listen to more than just Rangers fan media personally as I’d start to find it boring, repetitive and create a form of tunnel vision. I enjoy H and H but I don’t see myself as hostage to fan media channels just because it’s Rangers content I still enjoy content I enjoy and expand that beyond just listening to other Rangers fans.
Given the absolute wealth of podcasts available, that's still really a hard sell as a valid reason.
