Only means might be cultural. Security conferences such as DefCon or Black Hat create list of insecurely technology that is ubiquitousness and ignored by product designers and OEMs. Vote on ranking their priority and when they should be removed.
News would latch on to "Hacks say all computers without ECC RAM are vulnerable and should not be purchased for their insecurity. Manufacturers like Dell, Asus, Acer, ... are selling products that help hackers steal your information." "DefCon Hackers thank Nvidia for making their jobs easier ..."
Such statements would be refreshed during / after each security conference. There are over 12 conferences a year, about once a month these would be brought back into the public as a reminder. Public might stop purchasing from those manufacturers or choose the secure products to create the change.
