When people start selling Agile methods and trying to replace ideas with routines, meetings and paperwork - it is became a scam, of course.
But the ideas, on which Agile was built upon - like interviewing experts of the problem domain, extracting and preserving slang and vocabulary from the stories and keeping that terminology through data, code and even a markup by naming the same thing the same name everywhere. Design for changes, code for reuse, start early and iterate, adapt and evolve - all those ideas are working ones.
So, the problem is just with pre-packaged methods and forced techniques. Each group, each project should realize usefulness of some of those ideas by changing their habits and by practicing, not because some "guru" told you that something is such and such. It is the only way.
It is a common situation when some ideas replaced by routines and propaganda and authority of "teachers". Buddhism is the best example. The essence of Buddha's teaching is several simple ideas and conclusions from them. But in many places people have transformed them into sets of rituals, rules and endless empty talks.
