There is a difference I think in how people use evolution in the English language sense:
"evolution can refer to any sort of progressive development"
whereas in the biological sense you are right.
Since this is not about biology I figure we can safely assume that a 'progressive development' is meant and the article linked very much supports that.
The word 'devolution' is probably not used properly here, but I tried to indicate that I don't think this is 'progress', but rather the opposite.
