I would expect this number to be close to 0. What does this even mean?
I recall seeing a TechStars video a few moths back where one of the guys in the program all but admitted he was a software pirate.
My modus operati when I need an expensive piece of software is to pirate half a dozen different packages that claim to do what I want, evaluate them, then purchase the one that best does the job.
Wrong? Maybe. But there is a whole lot of hype when it comes to that sort of thing and I can't afford to weed it out at full price right now. Better (less crippled) evaluations (or evals at all) would help.
Sometimes I even find that what I thought I was trying to do was not what I wanted to do after all, but I usually end up buying something.
What do you even need to pirate to make a web app?
Rails, php, apache, mysql are all free
And YES I could just use Linux, before you ask, but I'm getting quite used to TextMate.
That's not to justify anything....but since you asked...
EDIT (can't reply to comment below directly): Yes, that's true. However you would still be in violation of Apple's EULA which states that you cannot run their OS on anything other than Apple hardware. So you are still being naughty by doing this ;-)
So because you can't be bothered with using something that's free, you are going to disrespect apple's license. There are plenty of free text editors for Windows and Linux that supports most of not all of textmate's features.
Many companies decide to use GNU code in their apps. They don't get the same luxury as you. Many are sued in court and others are forced to release their own code.
