Doesn't have to be "enterprise". Anyone can pay $5/mo for GSuite (https://gsuite.google.com), which includes gmail and a ton of other tools. Furthermore, it's on your own domain rather than @gmail.com, which is not only better (you truly own the email address), it's also a hell of a lot more professional and makes it easier to migrate to other services if you wish to.

To put it bluntly, if anyone here is complaining and has an @gmail.com address, email me and I'll be happy to help you buy your own domain and create MX records to either gsuite or fastmail. But I just can't hear the empty negativity anymore from consumers who say "no! bad google!", yet, by using the free product, keep making their emails available for the AI models and keep signaling to Google that an advertising business model works better than a paid-per-user one.
