Re: Is it the manufacturer or the consumer that has "no idea"?
The problem is, tell you average user they need a new firmware, because of a Telnet hole, they will tell you they use O2 for their telephone and they aren't old enough to need support underwear...
As the others have said, they buy the product assuming it works and will carry on using it until it stops working, just like a fridge, washing machine or TV...
