Hi, fair question. Lots of people are using the service in edu as well as commercial contexts. We haven't put any restrictions in that regard on it.

Other than that the plan is to keep this (or something similar) running as long as there is sufficient interest and so far there seems to be quite a bit!

Note that it does run on docker which means ultimately it's not fully "secure", but we hope to switch to hyperv-linux when it's available.
