I think it's hugely important to eliminate barriers to get access to education, which is why there's a free, web-based version of Hacktivate that is already being used 350+ schools around the world.

I also think there's a lot of people out there who would pay to have Hacktivate running offline, using the full power of their device, and with no external resources being required, so I made that too.

Suggesting that I need to make them open source to prove I want to help kids learn is really strange, particularly when literally thousands of students around the world are benefitting from my work without paying a cent.
