This is basically the design language their entire website had during the Leopard/Snow Leopard era. The website continues to serve Prototype.js and Scriptaculous.js, libraries which fell out of favor many years ago. It seems pretty likely whatever system was built hasn't been updated much in years, even though its content continues to be.

I don't know if that suggests they care or not. They care to continue to populate it with new releases, but not to invest in building a newer website.
