I don't think it's that nobody cares about the comics, but that they're not as widely marketed? I'll mention the different TF comics to people in passing and many are pleasantly surprised that such things exist and probably would have invested in them had they known about them sooner.

The medium in general is kind of underappreciated, tbh. Comics aren't the most expensive thing in existence, but if you get a lot of different series they can add up big time.
