leocharre,

there is a case to be made for the advantages of open source over commercially developed software. But you aren't making it, and you certainly aren't helping it by being borderline abusive and deliberately unhelpful. You can find a pretty good summary in the Richard Stallman quote from DigitalKitty's homenode:

"Proprietary software is unethical, because it denies the user the basic freedom to control his/her own computer and to cooperate. The problem with proprietary software is that a specific developer controls its development--you, the user, do not."
-- Richard Stallman

There are many reasons why someone would show up here looking for help with a piece of code they've paid for - perhaps the OP is looking at a piece of code that a freelancer has written? Or perhaps (he|she) or (his|her) boss has made a (possibly ill advised) choice to buy a piece of code that provides a particular solution.

I'm as much an open source zealot as the next monk, but perlmonks is a site about perl, not necessarily open source. Please bear that in mind, and either try to be polite and helpful to people asking for help, or if you can't, hold your tongue.
