Just saying that some random story is non-linear and the reading order is branching doesn't on it's own suggest hypertext. The only reason people are giving you grief over any of this is because you haven't properly explained how these stories not only use hypertext, but how they, in your estimation, fail to use it correctly.
And telling someone they're just "denying the presence of labyrinths" or saying "how dare you call yourself a Morrison fan when you don't even recognize blah blah Borges hypertext" isn't an answer.
You have to first prove that Morrison intended Final Crisis and Seven Soldiers to be hypertexts (and weren't just partially inspired or made some small reference to the ideas of Borges) before you can start calling the stories out for any supposed failings in that regard.
And we're all still waiting...
