If you're using e.g. Photoshop for your job, Adobe expects you to pay for the product... and if you're using it for private stuff, Adobe IMHO even wants you to pirate it (up to CS4.5 you only needed a keygen and a line in /etc/hosts, now you also have to patch a DLL file) in order to create a massive vendor lock in.
Microsoft followed the same strategy in China and elsewhere: create a massive lock-in, even if it means allowing piracy outright or just fighting it "pro forma", and when the people have enough money/education to use your product for business, they'll end up buying it because they're so used to it.
