I don’t think my sanity can take all of these explanations.

Though I just spotted one that’s worse than null being an object …

typeof Nan
"number"

I mean, come on… it’s even in the fucking name!

I’m no expert and I know that javascript is full of wtf moments, but please… Let it be B

It’s not gong to be B, it’s it.

There seems to be a few publishers missing here …

• Baen books (https://www.baen.com/) have never applied DRM to their books.
• TOR (https://torpublishinggroup.com/) stopped DRM on their books about ten years ago.

Baen typically sells their wares directly but TOR are through the usual sellers but have no DRM. I’m not sure how this works in practise with Amazon’s new “you can’t get the files” policy, but they are probably in cleartext somewhere.
