BG
BG, aka 'Bill Gates', also known as the 'Billionare Geek' or 'Boy Gumby'. Founder of Microshite. Recently, due to feelings of shame and guilt - accumulated over many years of pillaging and plundering all competition that stood in his way - plus an over-inflated bank balance and need for a good tax dodge, has created the 'Bill and Melinda Gates Foundation' to become the newly re-invented "Beneficiant Goodguy' in an attempt to atone for past sins. BG is also known as 'the scum that rose to the top' of the software dogpile.
Cheesed of Microshite user: "...man, why do we have to put up with this crapware!"

Bystander who knows: "Well, what do expect, BG and Co. never had it in their corporate plan to make bug free software. How else are they going to get into your pockets on a regular basis!"
