ePub certainly is not "Adobe's invention". It's owned by the
International Digital Publishing Forum.
ADE won't read all ePub books. It reads a subset of the ePub 2 standard, with perhaps the odd ePub 3 feature thrown in, but, to name but a couple of things it won't do, it has no support for either right-to-left or vertical writing systems (RTL is an ePub 2 feature, vertical an ePub 3 feature).
And that's not even mentioning incompatible DRM systems, such as Apple's ePub DRM mechanism.
