Software created in-house for companies, for "retail", and tools created for programmers themselves have very different constraints, and I don't think license discussions usually account for this. There's lots of software that would never be written for free, period. Open source projects are strongly skewed towards things that are useful for programmers, or at least fun or interesting technically. Beyond that, though. I don't know. My preference has been towards BSD / MIT licenses, but I also know that there's a fairly strong economic incentive for some people (web startups, for example) to use free software without necessarily contributing back - or even to take credit to look good to bosses or investors - and I'm not comfortable with that. It's a thorny issue.
