This definitely limits the usefulness of Google's "always free" tier. This will x2 some bills I have for small personal projects, though will still be a bit cheaper than an AWS alternative after the 12 month free tier.
Sigh.. I suppose it was a matter of time before they figured out the pricing loophole. Back to creating new Google accounts every year to get the year of credits...
They've since updated the language to keep free tier IPs free:
> Note: Starting January 1st, 2020, GCP will introduce an additional charge for publicly addressed VM instances that don't fall under the Free Tier. You will not be charged for other publicly addressed resources, such as forwarding rules.
