Yup. This should be considered bait and switch. It's fraud plain and simple and they should be severely penalized for lying about the services because "it's too expensive".
I would love to see this happen. How do we actually bring a class action or some other thing that effectively means they can't do this anymore?
This is something that should be under the purview of an agency like the FTC. If you are affected by this you could file a complaint with them.
Why do you need a class action lawsuit? Simply sue the company in small claims court. Why give money to useless lawyer? You can put more money in your own pocket.
$5k isn’t going to get Google to stop lying. A class action settlement might.
OP was storing 400TB of data. I think Google charges like $100 / 2 TB so that's $20,000 /yr. Wondering if that would go outside small claims since small claims is up to €5000
