It does nobody any good to have 1000 books on a single device if the whole thing is subject to revocation, especially when you paid full retail price for the privilege of being allowed to read it. This is regression.
Previously you paid your $10 and received a paper book. You could read it, re-read it, lend it, sell it, or burn it for warmth. You owned it for as long as you kept it dehydrated. The $15 you now pay per book gets you one of these rights, temporarily.
Whether most people can tell the difference between 320k and lossless is irrelevant-- the retail price is the same for a technically inferior product. This is a regression. And again, for your money, you own nothing.
And for apps, the cross-platform compatibility comes at the expense of consumers, who have to continuously purchase and maintain newer computer equipment to do the same damn word processing, email and shopping tasks that used to be possible on a 486. And of course, since everything is a subscription, it's a double punishment for the consumer-- they have to maintain hardware to run software they don't own.
The entire premise of modern technology has become a new vector to extract the most money from the consumer while delivering the least amount of value, power or control.
