It's like people have to be taught the same lesson about SAAS over and over and over again. Like what did they expect, to not get rug pulled eventually? Crazy. You own your shit or you don't. Simple as.
Removing some old book I had was the first major red flag.
My current kindle is my third one, and is the last. I will never ever pay for a kindle to Amazon, due to its user hostility.
Oh, and also you cannot move ebooks between accounts, even not with a lot of friction, eg. support tickets, which would be a fair way to game piracy and unwanted lending, which was some inconvinience for me in a situation. Not a huge monetary loss for me, rather a reminder that when you pay to Amazon (or Valve, or any other contemporary DRM-burdened vendor) you are only leasing...
I keep it offline in airplane mode permanently from 2016 and haven't seen a single ad in a long long time.
The ads are only shown while it's off, they're static black and white images, and 99% of the time they're for books. Totally unobjectionable.
If they were in the actual UI and for stuff like cars and perfume I might mind, but they aren't so I never cared.
Wasn't the original concept of the Kindle that it shouldn't need to be replaced by newer models?
You either die a hero or you live long enough to become the villain.
