Ask HN: Google Apps vs. Google Workspace

It's been a few years since I have used Google's business services. A few years back, setting up a Google Apps account for a domain was free to start (one free email and every additional email was a few dollars per user). Now I see Google Workspace doesn't have a similar option.

Bing used to have a similar option and I can't find what happened to Bing's counterpart at all.

What happened to this ecosystem?
