@email@example.com Well, I can’t agree on that one. It’s a ‘maybe’ since is hard to measure, but IMO we can’t say Zero evidence. There are some numbers showing that artificial scarcity has some impact on sales, and obviously, DRM devs want to sell their services, although they are biased. (I’m playing devil’s advocate here, making both positions to collide to reach a useful compromise)
My position is that DRM helps to prevent piracy among mainstream users, which would decide on renting Apple Music or Spotify vs using hipster alternatives. We as power users will find the best ratio between convenience and control. https://www.idealog.com/blog/drm-may-not-prevent-piracy-but-it-might-still-protect-sales/
I assume you’ve read this one: https://www.wikiwand.com/en/Information_Doesn%27t_Want_to_Be_Free I like it as my reference on the topic. Doctorow as a creator has skin in the game, so he knows about it and is a good influence on me as a creator as well.
