Not all companies get joy out of charging their customers to make their websites worse. Heaven forbid we're not all entirely motivated by money.
And these websites are not all "tuppenny-ha'penny". Examples I'm personally familiar with include Universities and companies with revenue between £5-80m / year. Updating their sites is not trivial nor is it cheap.
I despise the idea of a law we're told to obey, but expected to be cunning enough to avoid.
