You are kidding aren't you. You pay Adobe less than $180 a year for brilliant software and you are peeved. Are you peeved paying $800 registration for you car, $900 for insurance or $2000 for house rates? Dam if you buy a house you are paying 25K+ to the state government just for the property to change hands.

if Adobe charge $360 per year for their software, it would still be a bargain for what we do with it. GST is GST - blame the government but don't blame Adobe. Adobe are not profiting from the GST.
