How about the happy middle ground, the Mozilla Public License. Not anti-commercial, but still with payback. Commercial vendors can include your code verbatim in their products and not have to give any of their code, but any changes to your actual code do have to be published under the MPL.
It’s better than the GPL because it is more free. Anyone will be able to get all published versions of the code for free (if modified, must be released), plus people who use it in their apps have more freedom in how they license their original, non-modification code. There’s never any worry of “If I just link to it, does that make my code a derivative?” (different GPL authors have different conclusions about this).
It’s better than BSD because people won’t legally be able to take your code down a black hole, never to be seen again, effectively making a future version of your free software non-free. With BSD you don’t necessarily get anything back for your work, eliminating the capitalist aspect of open source.
