My guess as to the “why” is that it’s just another example of enshittification. Podcasts were essentially a bubble that everyone was trying to get in on, but the amount of low quality (not just production but also content) flooding the market devalued it significantly and listeners and subscriptions began declining. Everyone is trying to squeeze as much money as possible out of it now, which means there are even more ads on top of all the ads and cross-promotion that come baked into an episode.
I don’t know about the rest of Australia, but that’s not really the case in Adelaide. There is a pretty strong cycling culture here and a lot of proper bike stores for commuters, road cyclists and mountain bikers. Hosting the Tour Down Under for 25 years has really helped with that. But for whatever reason the government has never really invested in infrastructure that would help.daily commuters.
