In reply to Neo.

If a code is an open source under GPL, it's practically free. Even if the developer of that code does not offer it free, anybody else can. If anybody can, it means it's free.

If you can't find that GPL code for free, it's not bc. it costs something, just bc. nobody shares it with you.
In most situation the developer will distribute that code to you for some $ with some service or a nice word.
