@Rupert Goodwins
Reading the first lines of your article I assumed satire? Reading the rest of the article you seem to have a gushing love for dropping trow and grabbing ankles for the EU, but they are now looking to interfere with something you care about
"The principle of regulating digital products to make vendors take responsibility for cybersecurity is excellent but it demands proportionality"
Governments are not very good at the proportionality bit. Government cannot account for everything and thats assuming smart people with perfect information, far from reality.
