Thanks for the healthy dose of skepticism. We moved away from Github (their closed source policy always seemed fishy to me) and started hosting our own gitlab instance instead. Some products our students are building: llip.io and c0d3.com.
The students working on llip.io built an android/ios react-native app as well as a webapp. Everyone working on that project got a job, so there is no development on that anymore.
The remaining group of students is working on c0d3.com and running beta on it. Currently they volunteer at the library with FCC on Saturdays to get more people using it to improve it. If you want to meet them, show up for the Saturday meetups! https://www.meetup.com/Free-Code-Camp-SF/events/qzddrmyxpbgc...
I do empathize with your concern though.
