From that page “Anticipated Next Version: 4.1.3 (beta), February 2020” so this release as open source along with the github repo being set to archive/read-only looks like an “I'm done. If a community wants to keep this alive, over to them…”. Nothing wrong with that, it is much better than complete abandonment in such a way as other people can't carry the torch even if they really want to, but it is a less positive situation than the headline suggests.
