For me it is not really a problem of books, I did not read many books through Amazon, I usually buy them from authors, or just use the reader to read articles and PDFs. So the real problem yesterday was I wanted to finish reading an essay written by a friend and the book reader did not work.

So what is more justified is switching to a more open reading and listening infrastructure than Kindle and Audible (I use Audible a lot and there I lost access to books I paid for - not even with gift cards).

The real question for me is what is the best non corporate or self sovereign reading experience. Hardware will be probably Daylight, which I ordered and it will take some time to get it, until then I have my Pixel Fold with GrapheneOS.

But what about good user friendly reader app? When I see an article I want to read on my desktop, I clicked one button and then I could read it in the bed. 

 That too. I kinda enjoyed the comfort of being able to get digital content even if paid. (Why not support the authors anyway?) But if I can still lose it after purchase why not just pirate it? Amazon will have a lot of convoncing to do here.

I fell off of regular reading lately, so I'm not too pissed but I'll be more careful if/when I return. 

 I am an author and I do both Amazon and my own distribution through my web with woocommerce and @btcpayserver. When people buy from me directly, they get the files without any DRM bullshit. I try to turn off any DRM where I can (for example Apple allows authors to opt out from DRM and give customers pure epub). 

Also even people get the ebook from me, I get to keep 100% instead of 30% through Amazon. But for me it is more important that my content gets to whoever needs it, and Amazon distribution is what many people prefer. It's one click buying and have it in your reader user experience is great and people like to do things the easy way. It removes friction. But it is the infamous turkey problem.
