Re: Marketing opportunity
The kit was end of support in 2015. That meant, it had been supported for however many years and was then end of lifed in 2015, so probably a few years after it went out of production.
They didn't stop selling it in 2015, they stopped selling support and providing updates in 2015, so I'm guessing the kit is at least 8 to 10 years old.
And, at the end of the day, of course they are hoping that the customers will accept the goodwill gesture and buy new equipment from them, but they won't not give it to them or suddenly give them an invoice, if they go elsewhere.
And, if the customers are unhappy with the length of time the kit is supported, they should absolutely go elsewhere and look for kit with better support. But, if it is on the Internet (and doubly so, if it is providing your security perimeter), it needs to be in support and regularly patched! If it isn't in support and it isn't patched, you might as well stick up a sign saying "Fire Sale!" or "all you can eat buffett."
