The Amazon page is showing that these are being sold by GL iNet
Should GL iNet be selling products that have known security bugs and are past support without telling people? This does not seem right! I am sure I am not the only one to see these listed, and it would not surprise me that a new user of your routers would not know that this product is been sold without any support.
Just noticed that the page now says there are only 12 left, so someone has been buying these.
