The HN title is very misleading: It's a not actually a free tier, it's a time-limited, storage-capped free trial (separate from the normal $300 GCP free trial).

The HN title is very misleading: It's a not actually a free tier, it's a time-limited, storage-capped free trial (separate from the normal $300 GCP free trial). Therefore, I don't think that there's a risk of it costing anything. I guess I will say that I don't actually think that this is all that useful, personally, but I can see it as coming in handy in a very specific scenario.
