Do you really believe this is the main motivation behind people who are blocking Spotify ads? That they are sophisticated tech users who wish to express their distaste for intrusive script-based ads? Or is it simply because they want to use Spotify ad free without paying (in other words, engage in piracy to save some money)?

I find this rationale, while likely true for many readers on Hacker News, unlikely to generalize to overall population fo Spotify ad blockers.
