Premium doesn't have any of those ads. And if you're blocking their ads you're not paying with time and attention. Spotify seems pretty reasonable to me, it's free with ads or you can pay for a better product with no ads.
Sure it's adfree but the parent said "because it brings you value". Well so do I when listening to the ads. My problem is the fact they allow for JS and iframes.
For me personally 100% true, is it for everyone else is another question. If you are in a 3rd world country then it might be more cost effective to listen to ads.
