What about zerotier for an alternative? Seems to have a bit more market and mindshare (and thus perhaps continuity).

ZeroTier is certainly another viable alternative, but their self hosted option still relies on the ZeroTier root servers (you can self-host roots, but they don't support removing theirs [1]), and their licensing for the self hosted product is more restrictive than something like netmaker.
