Subscription based licensing is where most software will be headed. It reduces overhead costs (big reason) and allows a company to apply for a "Green" waste reduction credit on their taxes (small amount) by not selling a boxed version and not producing a large amount of waste in terms of packaging.
Overhead costs of a company are none of my concern. If a company can't manage their income & expense's, no amount of money will fix that. Infact, all it will lead to is price gouging in the future.
Now online only download .exe's for install is a good idea, no more packaging.
If you use their product it should be your concern as a consumer buying and using their product. If they cant manage their income and expenses I am not sure how money (which is derived from that) will make any difference. That result is form poor management and accounting which adobe does not have.
They are trying to prevent Piracy (which, in fact they are increasing) with the current model. Either way, $600/yr for software that would cost me and my GF close to $4500 every update cycle is very nice.
