The DRM is not saving any of these authors sales. I buy books because I want to not because DRM stopped me.

The problem for the vast majority of authors isn't theft, it's that no one ever discovers their book at all.

You’d think so, but that’s not the case. Here’s an example of a Canadian artists group that wanted “format shifting” to be explicitly illegal: https://arstechnica.com/tech-policy/2009/10/copyright-collec...

In their opinion, if you buy a book on Nook, then switch to a Kindle, you should be legally required to buy another copy if you want to read it again.

The MPAA/RIAA spend millions of lobbying dollars on trying to preserve their business model, to the point where non-US countries are required to follow their self-interested, business-model-preserving rules or be excluded from international trade deals.

If physical booksellers did the same thing, they would be ridiculed into silence by the sheer absurdity. But because it's opaque technical measures, backed by mega-corps, it gets a pass.
