If the Linux dream was to randomly pick versions of the kernel, deem them "unsuitable for public distribution", and not release them, sure!
I suppose it depends on whose dream they're claiming it is; much like the article notes, I'd imagine most people dream of it being a mainstream desktop OS (which it isn't yet).
Perhaps in time desktops will be irrelevant, but until they are, success in the mobile space doesn't seem like much of a dream come true to me, especially with the proprietary aspects to be paid.
