Proprietary formats also give the vendor more control. This is important on several fronts. The software supporting the proprietary format doesn't have to be as robust since people are usually using a common set of tools to generate and render the files. (Consider how different software renders ePubs differently. Consider how different web browsers render web pages differently, particularly in the early days of the web. And so forth.) It is also possible to unilaterally adapt proprietary formats, which is desirable while adding new features to differentiate your product from the competitor's product.
On the whole, I agree anti-competitive practices is a major reason behind proprietary formats. On the other hand, the issue is much more complex than that.

The reason Amazon and Apple use proprietary formats has nothing to do with what you described here. Epub2/3 were already defined when the K8 or whatever is called and ibooks were introduced. The only reason proprietary formats are used by these 2 companies is as a means to lock you into their ecosystem and hold you there milking your money for as long as they can. They don't want open standards that would let you shop for the best price.
