That has to be hyperbole: no one who ported J2ME apps would say what you did with a straight face. Even a run-of-the-mill app with no esoteric features would need to be ported because Nokia's methods had different signatures to SonyEricsson's for text fucking rendering, because why not. The entirety of J2ME an "OEM specific SDK" This is before considering MIDP, CLDC versions and goddamn model-specific processor and memory differences. "Android fragmentation is no different than J2ME used to be" my ass.

This is a huge overstatement. J2ME was fragmented in things like basic UI with no tooling to handle it. In Android you really need to dig into hardware-specific funcionality (or really really mess up UI design) to be severely affected by the fragmentation.
