I don't think that is their intention but yeah they need to clarify publish as sell or the start of sale. Later in that answer <For non-content patches (with the exclusive intention of keeping the game compliant with the current SDKs), post-launch, no license is required. However, keep in mind you won’t have access to the repositories if you don’t have an active license.> would suggest continued sale without license is ok.
