I don't disagree, but it's funny that Apple's AirPort routers, which have been axed almost a decade ago, can still be configured with the AirPort app. Years ago, I temporarily hooked up an old AirPort Extreme to replace a broken router, and it even got an update (probably a security update).

At any rate, I think as much as web vs. app, IMO companies should be forced to support their appliances for a certain time period by law (the EU has rolled out a law to require this for some device types). If it was normal for a router to work for 10 years or a washing machine for 20 years, a vendor should be forced to support it for that amount of time since the last sale.
