Google changes policy on essay-writing adverts

A few weeks ago I wrote about the problem of cheating and plagiarism.

Now I learn from the BBC that Google has changed its policy on adverts for essay-writing services.

According to the BBC article, managers of some essay-writing companies say they ar running legitimate businesses, and that they always tell purchasers that essays are to be used for research purposes only. However,

[the] university organisation, Universities UK, rejected as "absurd" the claim that students would pay "hundreds of pounds for model answers" and then not "submit them as their own work".

I must say that I am delighted by Google's change of heart. I'd like to se it as another example of consumer power, like the vegetarian revolt against Mars on animal products in their chocolate bars.
