Here are some lessons from this:

1) One of the most important aspects of software is support. No support means an insecure device.

2) Devices should state when they will stop receiving security updates. People should stop using devices once they stop receiving updates.

3) Do not buy from manufactures who do not state how long they support a product or do not tell you when they stop supporting a product. Note putting a notice on a page buried in a web site is not good enough. The product itself should tell people when it is no longer receiving security updates.
