This is a most excellent place for technology news and articles.
The problem is that it's impossible to support all products forever. There has to be a time that something turns EoL, and IMO 16 years is a reasonable amount of time for almost anything, but especially a small electronic device. As others have mentioned, it would be awesome if they opened the API for personal use, but there's a million reasons why that may not have been possible. Ideally everything would work and be supported forever, but it's impossible.
