Adobe comes down incredibly hard on businesses when it comes to pirating and they don't do so in the public eye.
If you're a production company and caught pirating by Adobe ~ It's very bad.
So while "everyone and their uncle" may have a pirated copy...Most companies certainly won't risk it, especially those that actually use Adobe professionally...
So, this is actually incorrect...And I, having once been the target of Adobe, strongly disagree that there's no professional consequence.
The 50$/75$ will change the market dramatically...Especially in regards to their market share.
I was referring to casual users who pirate, not actual professionals. I've never heard of say...a web design company pirating Master Collection, nor do I think businesses should go out and torrent it. What I meant was, Adobe makes X amount from the professional segment but have an additional segment of casual users who pirate the software, some of whom are put off by the pricing but would pay if it were priced lower, offsetting the lowered cost. PS is indispensable for a lot of things, no other software can come close. GIMP is absolutely godawful, and there is really no viable alternative to it for many people.
