Incorrect. Turning off recursion turns off forwarders, but not vice
versa.

You can have a perfectly operating recursive MS DNS server that does
not delegate recursion to any other server (forwarding amounts to
delegating recursion, but the server as a whole is still recursive,
thus the unidirectional relationship between the two settings).

You only MUST use forwarders if you are not allowed to pass DNS
requests out past your ISP's border (similar to when you have to use
the ISP's outbound SMTP gateway).

No, if you turn off recursion completely, you can't get responses for
domains that aren't on your box. No one is going to do it for you --
the "root servers" sure won't.

You're mixing up a lot of terms here. An open resolver is one that
will perform recursive lookups for any address on the open internet.

It's not "bad," it doesn't exist.

I doubt that...

... and there is no reason to go down this road. If you can get DNS
requests past your ISP, there's no reason to have forwarders.
