Yes, the repo readme says the code is open source but the fee is required for using the repo's issues and releases features.

I'd be surprised if the github EULA allows you to just attach rules to who can click the releases button.

For issues and discussion, sure that's essentially moderation. But surely you can't make a EULA that says you can't click on a github provided feature unless you agree to some arbitrary third party's rules.
