I've been reading up on this and am definitely not sure if serious...
Here's some software with a GPL license you may have heard of. Am I reading this correctly? It's legal to sell Wordpress (and any software with a GPL)?
Does the GPL allow me to sell copies of the program for money?
Yes, the GPL allows everyone to do this. The right to sell copies is part of the definition of free software. Except in one special situation, there is no limit on what price you can charge. (The one exception is the required written offer to provide source code that must accompany binary-only release.)
