I have been using it for 13 years and my account during all these years had only 1 user and I never used more than 13GB of the data. But since I'm using this email address for 13 years make paying my only option even if it ends up being paying another company.
What is illogical to me is why not offer the same Workspace Essentials Starter Google (without Gmail) is offering to anyone with a custom domain email right now as a downgrade option to legacy users. That's better than not having any data available, no Drive etc.
