You can get a Kindle for $110 with ads, or for $130 without ads.
As much as I hate advertising, this is as good as it gets
Creating a different experience around reading books for those who have and those who have not is also a problem, given how important literacy and the printing press are to the development of our society.
The first or last pages of books are still frequently used to sell other books from the same author or from the same publisher. Not that long ago they'd come with cut-out cards to mail in for your order for more of the publisher's books from the partial catalog printed in your book (nobody orders by mail any more, is the only reason the stopped that, I assume). Some of my books when I was a kid would have the first chapter of another book from the same anthology series at the end, to sell it (Goosebumps did this, for example).

It's not far off a hack. And not OP but personally I've got very few problems with getting one over on massive corporations like Amazon.
Likewise, businesses lose money on people who habitually return things. People who behave reasonably subsidize the "ingenious" minority. Generous warranty and return policies can only exist when most people behave reasonably.
This is actually a good description the behaviour of megacorps like Amazon. They are constantly looking for new ways to increase and consolidate market share, pushing or breaking the boundaries of anti-trust regulations, at the expense of the consumer.
I wouldn't advocate this sort of behaviour towards individuals or small businesses, only megacorps. Highly dubious that this would actually cause harm to the average person. If anything it would hasten the enshittification process, open the field up to competition, and be a net positive for society.
I am likely coming at this from an entirely different mindset to you. In my mind, the current economic structure implies that sufficiently large corporations are pitched in a battle against ordinary people.
When did that start being a thing? I've been using a kindle for about 14 years, my current one is a few years old. I've been thinking about upgrading, but it works perfectly fine, and I've never had it display ads, and haven't had to pay anything for that "privilege".
It sounds like this will be my last Kindle device if I now have to pay extra for no ads, on a device I've already paid for, to read books I also pay for.
When will the madness stop!?
