hi NicoEchániz here, project coordinator for the LibreRouter.
There are many different realities regarding the connectivity from a community network to the rest of the Internet. In the case of AlterMundi - the organization steering LibreRouter - , the communities that are connected in our region in Argentina are registered as a national non-profit operator, we have our own ASN and public IP ranges and we do BGP peering with other networks in the region.
So... no ToS violations.
