Bitcoin podcasts that take advertising money are no better or worse than anyone else that takes advertising. They're subject to the same forces and conflicts of interest.
That said, I like Swan and use them to DCA. I like their service and think they're good actors. The main reason I use them is because I think they're good for the larger ecosystem. I view the fees as basically a tithe to support that work.
(Although, despite using the word "tithe", I could do without the religious revival vibe of their conference. There's enough of that shit already in the industry.)
