This was written a year before Zynga was formed. I still think he's hypocritical, but let's be clear about the context.
>> sells spyware (Zwinky toolbar)
I have no idea where you got this idea from. Zynga does not make Zwinky, Mindspark Interactive Network does.
>> highly profitable add-ons to games under the pretext of charity (Farmville "donations" to Haiti)?
A 50% charity split isn't shabby. Sure, Zynga should have given 100%, but there are higher profile initiatives with MUCH lower splits. Product (red) is a great example where buying a $150 iPod nets a whopping $10 for The Global Fund.
