"Kindle for PC" to be discontinued and replaced by a crappy Microsoft app

I read all books on my Desktop PC on my 32 inch monitor. As of the 30th June 2026 the classic "Kindle for PC" app is changing to a Microsoft app. The below picture features the minimum size I can shrink this new Kindle window. 

The window is 42cm/16.5 inches across with the text 27cm/10.5 inches across. I can make it bigger both horizontally and vertically (though vertically it's already almost at its max). But I cannot make it any smaller. But I much prefer the window is somewhat narrower since 27 cm forces my eyes to scan across the page more than I'm used to. I typically have the text usually at about 20 cms width at the most and also with the window shorter vertically too. Furthermore, because this bloated new kindle window now covers about 2/3rds of my 32 inch monitor screen, it obscures other parts of my screen such as websites I might want to glance at when reading. 

According to Google AI:

"Mobile-First Design: The new app is essentially a Progressive Web App (PWA), which means it runs the mobile/tablet version of the Kindle code inside a Windows container."

And:

"Amazon prioritized a unified app experience across devices over the specific needs of large monitor users, failing to realize how stretched the text would look on a 32-inch display".

But it's supposed to be a replacement for the classic "Kindle for PC"! So it's supposed to be designed to be the kindle reader for those using a PC to read their books. This seems to me to be a pattern I've observed over recent years where companies appear to be trying to force people off their PCs (whether desktop or laptop) and to use smartphones instead for whatever reason (maybe it's easier to force people to see ads on smartphones?).  

Of course, this would not be problematic at all if Kindle ebooks lacked digital rights management (DRM). For then not only could people choose the size of their reading window, they would be able to:

a) Actually own the ebooks they have currently supposedly purchased and to be able to read them on any device.
b) Convert their ebooks to standard formats like PDF or epub, and to open them in browsers like Microsoft Edge where LLM's (like Copilot) can analyse and summarize the text.
c) Utilize Edge’s excellent, natural-sounding AI text-to-speech voices to read the text aloud—a feature that vastly outperforms Kindle’s robotic, built-in voice.
d) Be able to highlight text in green. OK..OK.. this is trivial, but I just like to highlight text I agree with in green, and highlight pink where I disagree! Why Amazon doesn't offer the option of highlighting in green is baffling.

I do appreciate that Amazon doesn't want ebooks to be shared.  But to be blunt, this is Amazon's problem and it shouldn't fix their problem by degrading their customers experiences, especially as kindle ebooks are usually the same price as their physical counterparts.

And even if we do have to suffer DRM, why can't the official Kindle apps be vastly improved to make the experience comparable to ebooks that are DRM free? Why can't people adjust the reading window to a size of their own choosing? Get AI to scan the text? Integrate high-quality AI voices that don't sound like a robot? I see no reason why being forced to put up with DRMed ebooks should lead to an inferior experience.
