G Suite for Business is an enterprise product costing $5-25/user/month with 24x7 phone support, escalation paths, contractual SLA's, etc. It competes heavily and directly with Microsoft. A company doesn't get "banned".
This smells like black PR to me... playing on Google's lack of support/transparency around free consumer accounts and trying to get people to associate it with their Enterprise division.
I mean come on, just the way it's written: "One of the girls at work was fucking bawling her eyes out since she couldn't access her e-mail either." and the final "I do not know why Google has a scorched-earth policy when it comes to this kind of stuff, but I fucked up and our boss is looking to migrate away from Google even though we just recently signed on not too long ago." It just feels too obvious.
(Also, G Suite for Business accounts don't have recovery e-mails -- your admin takes care of your account -- so the supposed personal bans sound made-up too. EDIT thanks to ballenf below -- by default users can't set recovery e-mails, but a G Suite admin can enable that option for their domain.)
