The best defense is a good offense. Get software patents banned, or get a bunch of software patents and donate them to the ASF. When Oracle comes to sue Apache for their free httpd and ASF counters by suing Oracle for something their billion-dollar-per-user database uses, the situation will probably be resolved very quickly.
That, my friend, is the most chilling statement I've heard all year. We all go about our daily lives thinking we're safe in our cozy open source worlds and believing the leaders of our projects will protect us, but when folks like the ASF are left quaking in fear, it really shakes your foundations.
How can we even begin to contribute? I can code all day, but IANAL. How can I help buy one?
