For the past two years, one of the only ads I've been hearing is about converting to Soundcloud Go +. It drives me crazy. The text is "do you want to listen to music ad-free? Then get Soundcloud Go +".
Ads are OK, just not the same one over and over again. It feels almost like indoctrination. Just start running ads on "climate change is real", so at least people learn something while being annoyed into a paying account.
