Amazon Illegally ‘Bricked’ Older Kindle Models, Class Action Suit Claims
(www.classaction.org)
This is a most excellent place for technology news and articles.
It's not even necessarily the end of support and updates for old products. If I have a Black and Decker drill from 1920, it's not reasonable to expect them to still service it.
But what is unreasonable is allowing Black and Decker to break my drill. And that's what Amazon is doing when they restrict access to content that was previously viewable on the older models.
