Response to: Dual Licensing

The difference is the airlines are selling tickets for travel, not software. The gaming company is selling software. The core business is different between the two. The gaming company is planning on revenue from what they sell (software) and MySQL wants a cut of the pie (maybe recurring revenue on subscription model). The other thing to consider is the airline prob. purchased the ticketing/web software from another party and the third party would (or should) have purchased a license.
