14 years support window is so insanely good. But as it goes...
You either die a hero or you live long enough to become the villain.
My local library has some dead tree format books with a 500 year support window. Or dead animal or dead reed format books with more like a 2000-year support window.
Planned obsolescence is always bad.
A bookshelf can have books that are 100s of years old.
Maybe for ebook readers, but not for books.
I think the bigger issue is that there's market segments that old product reached and that newer ones don't... and you are locked into their devices by the content you've "bought."
14 year support window is pretty good. Not being able to get a modern device with buttons, and having no way to read your books with buttons, isn't.
