I am sure some will hate this but the elephant in the room is embedded devices including network device are incredibly insecure and do not get updates.
Google appears to be taking security and home networking to a new level. But most "techies" know far easier to do insecure then secure. Nobody complains when internet works even if insecure. Seems like a bump in the road for Google in pressing forward with this.
Some will think crazy for a Corp to be basically running my home network but for me I have better things to play with so go at it. But last night glitch needs to be a one time thing.
But most people seeing a blinking blue light are not going to think "oh, I'll just open the WiFi app and a new network in setup mode..."
