This is written by an ex-employee.  I don't know whether to laugh or cry at things like-

Voodoo5 6000 cancelled because there were a few motherboards with a faulty AGP implementation (fixable with an updated BIOS) that wouldn't support the card

or

$30,000 to $50,000 being spent a month on company lunches

or

the Rampage having its DAC flipped so that the final design would have had to have had a reverser fitted between the VGA socket and monitor cable.

I suppose it is funny and sad.  But that company had a loyal customer base that most businesses would kill for.  And what they did to them makes me  >:(
