Honestly, I hate "free tiers" for SAAS products like this.

For about 5 minutes, Google had a pay-as-you-go service on GCP for git. I used to use that, because I wanted to own my stuff. But (I guess) because everyone used "free" github -- and like a lot of other Google services -- they sunsetted it.

So now I'm using github for free. But would rather pay for my storage an usage with a (big) cloud provider.
