You're telling like they didn't send tons of notifications emails before they did so, eh? And after they "nuked" (you lost your access), you still had months of time to pay and restore access.

And besides, if it was your private domain, you could submit that to google (I didn't follow up, but perhaps they spared the nuke for regular folks who just used their custom domain with gmail)

I am more worried not having access to my REGULAR Gmail account, with none to contact with, rather than G Workspace.
