I've officially posted the license for Laser: AGPLv3.0 with commercial exceptions.
I don't have a commercial license prepared, but I assume that anybody willing to purchase one probably wants it so they can make money with Laser, so if that happens, I'll pay a lawyer to come up with a license. However, I can assure you that license will not include any guarantee of support, upgrades, or even future communication from me. It's just so you can get out of the AGPL.
My perspective is this: I think Laser is going to make a whole bunch of open source projects totally awesome, the more it gets worked on. As it grows into a general-purpose linter and analyzer, I can't imagine not having it be freely licensed. I wouldn't have worked on this project in the first place if I didn't believe that the Ruby community needs it. How could I ask the average Rubyist for a check?
Besides, I don't really think there is much of a market for commercial licenses for Laser, except for a few companies currently making commercial Ruby tools. So I'll keep the door open. If you want to make money with Laser without sharing your code, throw a piece my way. The rest of us will share the fruits of our freely-shared labor.
