I did read your comment, but making money from speaking about software is not selling out to me. Is that what you meant?

I think open source works best when folks don't expect to make money off of it. I don't think Linus or Stallman expected to make money off of their free software. In some cases you might be lucky and able to get consulting contracts from firms related to your open source code but it's not reasonable to assume that will happen. It's possible it's harder to get lucky today than before but it was always unlikely.
