The problem is the UK
did adopted the law, it's just the EU law in question
doesn't create an obligation on sellers to provide a two year warranty. The EU law says is that consumers cannot be limited for bringing a claim for a defective product for two years, that isn't the same as saying any consumer goods should last for 2 years. The existing Sale of Goods Act 1979 gave people that ability here, and the limitation period was already 6 years.
Directive
1999/44/EC (link to English language PDF) is the one that has caused all the problems- people incorrectly interpret it. Apple's one year warranty is
in addition to statutory rights like the directive above. Plus it's the seller not the manufacturer that the law applies to.
I agree with the criticism to an extent- Apple (and other sellers) should make it clearer that extended warranties are sometimes not necessary and there is often still recourse for consumers without them. Moreover, they should make their staff aware of the statutory consumer protection laws so you don't have to threaten to start legal proceedings to get something done!
