have you considered offering a VPN service? The Calyx Institute is a non-profit offering such a service and then there’s also the one from RiseUp.
I am on the hunt for a VPN, and i’d be willing to pay for it.
I was going to use Mozilla’s, but their linux support isnt quite there yet. Also, Mozilla doesn’t support openVPN.
I actually use Calyx for my phone, it is a good service.
At the moment we do not have plans to offer vpn service, specially that running one free of chanrge adds ton of issues with abusers and other to the mix.
It is something many poeple do request and something we should look into. Just for now, we are already busy as is.
