Is it clear whether the Debian image sources will continue to be maintained?

I do not see direct statements that they will stop maintaining sources in open source.

We'll see :)

		It is at the top of the announcement. This only affects OCI images, not source code "The source code for containers and Helm charts remains available on GitHub under the Apache 2.0 license."
