> Given their business model, it makes lot of sense not to support epubs
Which "business model" is that? Being monopolistic through their own proprietary format? Yeah, monopolies don't want to give up their monopoly power. Go figure. That doesn't mean we shouldn't be demanding that their power is reduced.
But they are using their proprietary format to promote their platform and as soon as you are in their walled garden, it's much more convenient to buy it from Amazon.
They are a content provider and they do anything that's legally possible to keep their customer and that includes a proprietary format.
Given that the Kindle is currently the best e-ink hardware that is out there and even by a big margin, they don't need to enforce anything (the Calibre plugin that removes the DRM from Kindle ebooks for ebooks) but I wonder what happens if a viable competitor turns up?
