I don't think this is true. I just tried to sign up and it says

Payment/Identity Verification - You will not be charged
You won’t be charged for using OCI Free Tier. If you choose to upgrade your account to Paid tier, you will only be charged for services used over your Always Free limits. If you don’t upgrade your account to Paid tier, you will continue to have access to Always Free services.
You may see a small, temporary charge on your payment method. This is a verification hold that will be removed automatically. See the FAQ for more information.
We recommend double-checking all the information before submitting the form since some info is automatically filled.
Oracle does not accept any virtual, prepaid or single use cards in payment verification.
Debit cards that have a logo (for example, Visa, Mastercard, Discover, American Express) and don't require a PIN number can be used to sign up for a free Oracle Cloud Account.

So it does require a credit card for sign up.
Additionally, it's next to impossible to spin up a free instance even if you provision it under the limit. Every single availability zone in the U.S. have all been constantly "emitting out of capacity" errors for free tier resource allocation. Ironically, if you provisioning beyond the free tier, they are ALL success.
So it looks like Oracle shawdow banned the free tier (or only allow a fixed set of free tier resources that are completely saturated all the time (unless someone spin down their free tier instances).
A small, temporary $100 charge, lol. Gave me a little shock when I signed up as a student.
The idea that a company would give compute away for free without one-or-more underlying motives is incredibly naive.
The users of this are not owed anything.
Though I can also confirm the provisioning behavior for PAYG vs. trial accounts w/o payment info.
Btw make sure you crank up the SSD speed all the way, as long as it is in the always free limit, you won't be charged for it ... Even though it says you will.
A "free tenancy" has limitations: e.g. your provisioned Free(tm) resources can suddenly be yoinked in order to satisfy an allocation from a user who's in a paid tenancy, even if that allocation also fits inside their Free(tm) envelope and ends up costing $0.00/mo. Simply put, the "paying" customers have dibs, even on free stuff.
Adds up.
"Always Free Ampere A1 Compute entitlements have changed. This update does not affect your paid resources, existing paid workloads or bill. Contact support for further questions."
Some people say that doesn't apply to PAYG users, I do not know about that for sure, I am a PAYG user since 2021 and have not experienced any reclamation issues.
Load average of ~30% per core seems to have been enough to repel the elephants.
