Later they say "They also both, mostly, focus on characters who have enough privilege to have choices, but not enough power to escape circumstances. Characters in both aren’t peasants without agency, but they’re also caught in larger systems they can’t opt out of" But that just describes basically everyone, none of us have no agency, but all of us are also caught up in larger systems we can't opt out of. But even within Austen you have Emma, who is entirely economically and socially secure and doesn't need to worry about anything and Fanny who lives entirely at the whims of others.
