While you're right that Morningstar definitely comes off as someone who read a few of the more sensationalist headlines around the discovery of
GFAJ-1 without bothering to understand the real work that had been done, I also think he has a bit of a point.
The way we determine whether or not there can be life on other planets is based exclusively on our understanding of life on this planet. It's
understandable. The carbon-based lifeforms of Earth are our only point of reference so anything else would be, literally, pure speculation.
HOWEVER, that doesn't mean that all life out there is consistent with what has developed here on Earth. There may be a planet somewhere where
boron-based lifeforms are the standard and that any air with too much oxygen and not enough ammonia is considered to be highly toxic.
Heck, Mars could be teeming with life, but the lifeforms look like rocks and they live life on timescale that we would think of as geological rather
Still, GFAJ-1 is not "proof" of anything at this point.
