Hypothetically, you don't even need fancy cracks to get a free copy of photoshop, all you need to do is to block the ports that allow online verification on Adobe servers, and then use literally any valid activation key.
It's a very easy two minutes process that anyone can be told, you just need to find the information somewhere (and this specific method has a lot of misinformation going around, so most people use cracks anyway.)
As Alex said, piracy actually allows a wider public to become familiar with it. Once you use it for commercial purposes, you have no choice but to buy a license anyway, and you'll be much more likely to do so (as opposed to choosing a cheaper alternative) if you're already familiar with the program.
