We'll be revising our free storage model in the future to accommodate more open source usage. There are a lot of base layer images people use that are built on GitHub and should be freely available. Those base images should become part of the public space and you only pay for private storage built on top.
This is good to hear, and makes sense to me. I'll also admit that, now that I've thought it over, I'm doing a bit of apples-to-oranges comparison, given the $4/mo is not just "for 2 gigs of storage," since it also includes Actions minutes and I think a few other bonus features (private wikis?). At that point, it's more fair to compare it to what e.g. GitLab offers, than what you'd get from Azure Container Registry or similar.
I'm not sure the Container Registry on its own will necessarily be attractive to people just looking for commodity-priced container storage, but GH Actions + Container Registry does make for a pretty compelling CI/CD story, I have to admit.
