Depending on where you are in the world and how much money you have, it is very good to support these companies. We all have had some purchases we regret, but overall I do not feel any regret about the majority of the software I have bought, even if it may be money lost. I have bought many other junk, but at least these purchases we make in software eventually lead to advances in technology or new plugins for us to use.

Your money is power... Be wise who you give that power to.
A lot of these developers deserve it. If I could, I would buy almost every plugin.
Much respect to business owners that do so. I am a little envious.

Ironically, people are quick to buy the software that has iLok rather than the software without any protection.
People want what they can't have, right? *cough* oeksound *cough* *cough*
