If a user logs in through Facebook or links to Facebook in the account
service, should we logout the Facebook when the user logs out? My
thinking is that we should otherwise that machine will keep facebook
logged in.

Actually its just account linking that is effected. If you log in
through Facebook, you will log out of facebook. I assume we want a
logout to happen to linked accounts too.

IMO the logout of child broker should be propagated to parent broker
logout just in case, that parent broker was actively authenticated
because of child broker.
In other words, when I click to "Sign In with Facebook" on Keycloak
login screen, but I am already authenticated to Facebook (hence no
Facebook login screen is displayed), then logout from KC shouldn't
logout me from Facebook IMO.
However I don't know if it's possible to detect this. In case that
Keycloak is used as parent broker, we have "auth_time" as a claim in the
token, so we can decide if parent Keycloak broker was actively
authenticated because of our request. Not sure if Facebook, Google,
Twitter and others OIDC providers have something like this. Also not
even sure if Facebook (and other social providers) allow you to logout
their session from the "child" app...

+1 to Marek, if you logged in in keycloak through identity provider like
fb/google/github/whatever user'd be greatly annoyed by logging him out from
fb (and all applications which used that login that don't go through
keycloak) just because user logged out of some keycloak-integrated
application.

Like marek said, you can't really tell if facebook was already logged in
or not. IMO, it is better to annoy the user than the alternative of
somebody taking over somebody's Facebook account because they stepped
away from the computer.

Both options are quite bad imo. But likely better to prefer security
over usability...
Btv. It looks that currently we never propagate Keycloak logout to
Facebook. And probably it's same for other social networks.
It looks that FB has some possibility how to propagate logout and it's
even able to divide between the cases when user was already logged or
not. There is this for Javascript API [1] and some possibilities here,
which may work for server-side apps too [2] . But it looks that you need
Facebook accessToken to logout.

As user scenario, user logged twice, first time as keycloak user and the second time as FB
user to provide auth to keycloak. And i`m, as user, remember, that i`m logged into FB. In
case when sync keycloak logout with social I will be surprised, If opening FB see login
page again. Also, I can working with keycloak secured app and FB at the same time ( ex.
serfing news on FB ) and It will be bad, if FB-site logout when I logout from keycloak.
