CS4 to CS5 Upgrade - What a Joke/Rip Off

What a joke. The service at Adobe is unbelievable, a purchase of $1000 software less than 43 days ago is met with a 30 day limitation on a free upgrade. This is the way they run a business. I understand no one is forcing me to upgrade but at a cost of $500 is ridiculous. Their so called teir system should be fairly based off of purchase date not version. Provide some fair pricng for someone in such short time range. An upgrade of half the price is ridiculous. Consider my business gone forever.
