> If a vendor goes under, I can self-host.
It's worth mentioning that this is true -- to an extent. Under ELv2, if the vendor goes under, you can self-host, but you will eventually lose access to any features protected by a license key if/when that license expires, since said vendor can no longer renew said license.
This was one of the main drivers for me writing the FCL [0], which undergoes DOSP [1], even for the protected features.
