This is a confusing claim. Are you saying the chosen license (<https://github.com/HermanMartinus/bearblog/blob/998e87263248...>) makes the software free to use to offer (e.g. gratis) "hosted or managed service[s]" so long as one does not sell the services? This is trivially confirmed not to be true. It prohibits all use of the software to provide services, not just a prohibition on selling them.
