idunning this is very well articulated. We are completely committed to open source, and working for ourselves just is so much better.
As for JuliaBox, we are grateful to AWS for the credits. They rescued us once, but going forward, we have to figure out a way to make it self-sustaining. I feel it is reasonable to have some level of sustainable free JuliaBox access, with charges for higher compute and storage - kind of like github, although it is not an apples to apples comparison.
