Officially it's not available anymore. But there are team plans that are not enterprise, so if you are small enough and fine with the data protection included in those maybe that is what you're working with? And I do know NGOs were offered seat based plans after they were officially not available anymore.

Also: This change came in in March so if you got your contract before then this will only bite once you renew.
