Is it the manufacturer or the consumer that has "no idea"?
"... of course most consumers have shown they've no idea about this stuff by failing to install much-needed new broadband router firmware despite colossal security holes."
Is it that they have no idea, or is it that they have a different idea? I suspect that many consumers actually have a good idea. They think that when they buy a product it is finished and ready for them to use. The idea that it's simply a proof of concept and a work in progress does not enter their minds - and I can't say I blame them.
