I would wager that most of the people that put the time to put these test cases together also get paid to handle these problems and build solutions. It's a giant misconception that open source is written by a bunch of hobbyists in their spare time on the weekends.

Most open source gets written by professionals employed to build something, and the open source work is part and parcel to their day job. I send patches upstream to the open source libraries and tools I use all the time. This is all happening while my employer is paying me to be on the job, and in fact is heavily supported by my employer.
