It's 5 years from End of Sale, and not just 5 years from the initial sale date. It sucks for those that bought the router close to End of Sale, of course.

Don't know for how long these routers have been around, but for one of them I found a overview document dated 2011.

If I buy a washing machine and it breaks after 4 years, it doesn't matter that the model is 10 years old at that point. My rights are from time of purchase.

Should be same for devices. If not, they should at least carry a "best before date" like food, so you know at time of purchase how long you can expect to get updates.
