I've been warning people about DRM since day one. Never say "MY Kindle library", "MY steam games", etc. They are not yours.

I didn't believe they would break the social contract and I was wrong.

I lost so much in money and notes when they decided the books I bought "to own" were now considered "licensed".

They changed the encryption on most of the newer ones so I couldn't even retrieve most.

They also took away USB transfer so I couldn't use the library system in the way I liked.

Now? I own a Kobo which will never touch the internet for the rest of its life and it only contains epubs. One day, Kobo/Rakuten will likely do the same.
