If you are already a customer of Oracle, I can't imagine this matters to you. You did not choose Oracle because it was a good product and they are a good company. You are a customer of Oracle because there was a backroom executive deal with the Devil. No one is surprised or outraged or even has any choices.
I've started seeing ads for Oracle OCI in some podcasts I listen to so I think they are starting to see if they can attract customers outside of their "enterprise sales process".
I'm not sure who those ads are supposed to appeal to besides the podcasts hosts raking in the ad dollars.
I haven’t seen the ads, but Oracle Cloud is definitely the public cloud provider with the most generous free tier. That’s not to say you should use and trust them, but I can see why many would.
My personal multicloud strategy for many years was to make full use of the free tier on as many providers as necessary.
Making a cloud provider that just wraps other providers' free tiers would be a fun challenge.
