The futo temporary license is not very open at all. Yes you can view the source code, but the license can be revoked at any time. So this is basically source available for auditing, but no community should use this code / project to build any modifications, or forks, or anything contributing to the ecosystem.
It's great that futo is innovating, but I want to make it clear its not open source by the standard meaning.
Maybe a better term for this type of "source viewable" closed project would be "source verifiable"
