They are not limited to people in squads. Even the current TOD series which is squad based is not limited to only participating squad members, you can join as a guest of a squad.
The new scenario starting up, Big Week, requires registration but is not restricted to squads.
The mini-scenarios that are run weekly, Snaphot and Check Six! events, are never restricted, they are simply walk on events.
Hope this clears up the misunderstanding...

P.S. At leat one squad is asking for guests for this week's TOD in the general forum atm.
