No security updates either? Even normal updates in general can bring better performance, user experience, etc.

I don't think anyone actually WANTS updates to their device. But I'd certainly prefer that I be ABLE to in case some sort of catastrophic security failure occurs like the router having the telnet port open or a default root password open. I'd much rather have something that can be patched than something that is "locked down" yet vulnerable.

And yes, I'd prefer that the routers not have security holes in them in the first place. But I'm also realistic.
