Overview
Google caused a lot of controversy when it decided to phase out the free edition of their popular G Suite (Google Suite / Google Workspace), which they had previously grandfathered in for personal users who acquired it when the solution was still free-of-charge. Many relied on the service for custom domain email management using Gmail behind-the-scenes, and others for the Office-like suite of web applications for word processing and spreadsheets (Google Docs, Google Sheets).
In my case I had a couple G Suite accounts tied to my personal blog and portfolio domains, and have had them since the beginning of G Suite. Back in the day, they were offered as a free service by various hosting companies including my personal recommendation of Dreamhost Shared and Dreamhost Dedicated (affiliate links). This is why it was so unfortunate to see that option phased out many years later.
