Whoah there, no, no, no, you couldn't be more wrong. The GPL
isn't about Open Source, it's about Free Software, which means
that the source (or an offer to provide it) *must* accompany
any distribution of GPL'd software. You can't make closed
source products out of GPL'd code. You *can* make commercial
products from GPL'd code, but you must provide source, and the
product must be freely redistributable. See

The BSD licence is a different beast. The BSD licenced allows you
to make changes and not release the source, or appropriate bits
of code you like into your closed source product.

They're both "Open Source" licences, but they're different in
intent and philosophy. GPL'd stuff can't be closed off, BSD'd
stuff can. You don't want the full argument....
