This kind of what's-a-good-word-for-it behavior is what makes me wish upon a star that microsoft would slide into irrelevance already and leave the software industry alone.
I think the point he is trying to make is that MS falling into irrelevancy correlates with something else replacing their products, thus, the alternatives in this scenario are better.
It's a nice thought, and not en entirely pointless one. The more population that migrates to alternatives, the better those alternatives become. Of course it's not linear, but right now it's all likely positive gains.
