The title is misleading -- one developer (a major one, mind you) is stepping back from offering free community support. This is not "Apache PLC4X" announcing an end of community support, it is one of the core developers announcing he will be doing so.
To be fair, it seems there is just about ~5 developers who have contributed more than 100 commits(https://github.com/apache/plc4x/graphs/contributors), with only three of them working on it for longer than one year. So it seems Christofer is just about the "core development team".
Looking around at the website and the GitHub repository, I can't find a single place to get community support either, it seems to only be commercial support now, so it seems Apache PLC4X is indeed no longer offering community support.
