> Why I (A/L)GPL

> Open source to open source, corporation to corporation.

> If you do open source, you’re my hero and I support you.

> If you’re a corporation, let’s talk business.

> I want people to appreciate the work I’ve done and the value of what I’ve made.

> Not pass on by waving “sucker” as they drive their fancy cars.
