Maybe the direction Apple and Microsoft are taking is not aggreable in that both are seeking tighter control over what we do with our computers. Both are businesses and obviously will try to extract as much money from us as possible. In the case of Apple, their computers are increasingly closed boxes that cannot be opened and repaired. Instead you're faced to pay ridiculous prices for upgrades and repair, which lines Apple's pockets at our expense. As a what if exercise, I'm thinking over what it would take to supplant macOS with a Linux system (won't ever go back to Windows).

Electronic books are a big thing, making it possible to own a vast library without the bookshelves. The Kindle marketplace is the largest e-book marketplace, and unfortunately Amazon does not support the industry-standard eBook format, EPUB3, and instead stays with its proprietary MOBI-based eBook format. Reading Kindle books, then, requires using a Kindle device or a Kindle application. And, of course, Amazon doesn't make a Kindle application for Linux. Since we are pondering a switch from macOS to Linux, how do we solve this problem?
