alt Hacker NewsWon't the supply-side incentives misalign with demand-side's desires in this case?
If you choose a specific company's free tier, you can rely on reputation and switch if they misbehave (e.g. they exfiltrate your secrets, log all your activities, build a profile on your workload behavior, etc). But if you don't know where your workload being deployed, the operator has less incentive to treat your compute with respect.
Means this is really only useful for nearly-public workloads, where tampering is not a critical failure mode.
That is why unless you own it yourself, a "free tier" is not truly "free".
This service uses GitHub Actions and it is likely against GitHub's terms of service and GitHub can pull the rug if they wanted to.
If you don't own it, there is always a catch when something claims to have a "free tier". This is one of them.
