I'm not all that familiar with the field of law but I'm almost sure the "pro bono" work does not compare with the amount of effort that developers put into open source projects. And even if law is an exception, just consider a lot of other professions, accountants, bankers, managers etc... How much open-source-equivalent work do they do? How much do they have to do? What have been the achievements of any of this work for other people (if any)? Compare that to the things that open source community have achieved, entire billion dollar companies are relying on these technologies that started off as hobbies or what not and are maintained and developed further by the community. Given the achievements, I think we deserve a lot better than what we are getting.
