I was thinking the same thing. I once worked at a Silicon Valley company where the CEO spun his firing by the board as a resignation due to a serious personal illness (complete with public tears and hugging the founders during an all-hands meeting). It was quite a performance, but not everybody was buying it.
That was my first reaction as well, but I'm going to leave cynicism to the side here. Faking cancer is ways and leagues beyond faking a CS degree and I just don't want to spend the energy required to believe anyone would do that.
