Cheri Baker writes about Spotify in Dear Podcasters…:

I fear we’ve seen this scenario before. A biggish company decides that they’ll aggregate an immense amount of creative work and monetize it. They’ll offer you tools to make “sharing” easy, and at first the terms of service will be reasonable. But once they’ve eaten a big enough chunk of content, they’ll lock the gates tighter, change the terms of service, and monetize the audience. By that point, customers would feel locked into Spotify, and podcasters would be afraid to leave.
