GPL license

GPL stands for General Public License. Code under GPL license needs to be made available. It doesn’t mean that a company cannot charge. Yes, it doesn’t make sense to charge for the code, since it is available and everyone can download it for free, however a company can charge for a support contract. Good example of that is Red Hat Linux. The code of Red Hat Linux is available, however a person that needs to receive support from that company needs to pay for support contract.

It doesn’t make sense to pay for support contract for personal use, however companies may chose to pay for support contract. If there is an issue that needs to be addressed quickly, than there is a company behind that product, and there is a good chance that they will resolve this issue.
