It's the combination of requiring Proton servers and the fact that that there is no public release of server source code or specifying which open source software runs on Proton servers, amount to a type of vender lock-in
RiseUpVPN uses OpenVPN from Bitmask so everybody can duplicate the service using their own custom build version of OpenVPN to connect to RiseUp servers so their server's code is publicly accessible.
you can do this with proton servers as well. they offer openvpn and wireguard. iirc, the "non-free services" is because the "Alternate routing" feature in proton apps routes over Google servers. if you disable this option it goes directly to their servers.
