I buy from Amazon a lot and simply remove DRM and convert, all within Calibre.
If I did not have that knowledge, then there are a number of ebookstore alternatives that I can use, until I do gain that knowledge. Outside Amazon ePub is the standard.
To be honest though, a number of Kindle users I know do not care about alternative places to buy an ebook. They simply go on to Amazon and buy that ebook and within minutes they are reading it. That alone is certainly the most powerful feature of Amazon's ecosystem whatever other shortcomings there are.
