Deceptive writing. It's just the outdated (and presumably insecure) Hive Nano 1, that is being deactivated early, and for a good reason probably. The author should explain the necessity to switch off insecure products and motivate people to stay up to date in terms of IT security. Instead, the text makes it sound like some villain corporation is trying to screw their customers for no good reason at all.
Apache Causeway [1] generates a RESTful API that is HATEOAS compliant, and exists in parallel to the built-in viewer that is based on Wicket.
There are a few HATEOAS client projects out there, such as [2], that will generate a UI from such a (Restful) API. As far as I know it works quite well, but of course it's a bit rough on the edges.
One interesting observation is that the Wicket UI generated by Causeway does not itself use the RESTful API, but it uses the same meta model that is also used to generate the API.
