Doesn't your boycott of the ad-free model confirm to them that the only viable business model is ads?

I'm not sure where you got the idea that I'm boycotting "the ad-free model".

I'm boycotting them. After all, every cent that goes their way supports surveillance advertising (among other unsavory things).

I have other subscriptions that support ad-free creators.

If they choose to misconstrue my refusal to support them with either money or ad views, that's also their problem. (Also, that's patently never going to happen, because my signal vanishes instantly into the noise.)
