It remains a technological product, though, and one doesn't like to buy into tech ecosystems without a full assurance of ongoing support. Chromecast Audio being discontinued today is one thing, and Google does promise continued support for the product … but Google's track record may not bear that out.
In the case of some sort of critical security update or a theoretical future update to pick up a hitherto undetected, show-stopping bug, there's little assurance Google would look after its customers — they've too much of a tendency to introduce something then rescind the product not long later, something that doesn't inspire much confidence in whether or not there will be ongoing, high-quality software updates to support the products.
