I guess that further bolsters the point that FOSS isn't a cure-all for ed tech. A for-profit company that can reduce training costs by half would be much cheaper than a FOSS solution that requires more training.
FOSS movement is dominated by geeks. Fine with me, I am one as well. But the relative dearth of artists and UX designers results in very well written software that users struggle to use.
Training is expensive.
