Kobo also has audiobooks

Not for audiobooks sold through Audible, for reasons Cory Doctorow has discussed at length:

Today, Audible dominates the audiobook market. In some verticals, their market-share is over 90 percent! And Audible will not let authors or publishers opt out of DRM. If you want to publish an audiobook with Audible, you must let them add their DRM to it. That means that every time one of your readers buys one of your books, they’re locking themselves further into Audible. If you sell a million bucks’ worth of audiobooks on Audible, that’s a million bucks your readers have to forfeit to follow you to a rival platform.

Libro.fm rules, been using it for years now. Same price as Amazon, has a vast majority of the books I've been interested in, and you get to pick a local bookstore to support and some portion of your subscription goes to them. Since we're on HN, you can actually download the audio files from Libro.fm as an officially-supported feature also for backups.

If the publisher decides to release them without DRM, yes.

In other cases it's not difficult to remove the DRM yourself.
