Just great.
I've not received the email yet but I think I am on the free G Suite tier. I joined (March 2012) way back when it was Google Apps just before they stopped offering the free tier in December of that year. I am a home user, my "organisation" in G Suite is myself and 3 other family members who use less that 1GB of G Drive storage and nothing else.
I've used it mainly so I can have my emails from my domain name (also now hosted by Google Domains) forwarded on to my GMail, and I used to use a bit of Google Drive storage (I've migrated that over to using One Drive as I pay for Office yearly so get the 1TB of storage). Not exactly a heavy user. :)
So, I will not be paying $6 a month for this. I will have to migrate my data and go somewhere else that offers a similar service for free. If that means binning off GMail and the other google provided services, so be it.
I think myself, and possibly many others waking up to this news today, would appreciate people's advice on any alternative free services for those like myself that use G Suite mainly for email with the ability to use your own domain name. If anyone is aware or can recommend any solutions, please let me know via the comments. Or perhaps this is something El Reg can knock up for a future article? I'm sure I wont be the only one who would appreciate the advice.
Whilst i'm not adverse to spinning up a linux VM and creating my own mail exchange (i've done this in the past), I would prefer a hosted solution rather than relying on my home infrastructure and being at the mercy of Virgin Media reliability. :)
