They buried the lede - piping is flourishing in "rural communities and private schools", where it always has -- the authors (and/or their purported source, who may be looking for government grant money) are actually concerned that pipes are too "elitist" and not "diverse" enough, and that the hordes of Muslims and other non-Caledonians are not going to take up the pipes in sufficient numbers to calm their poor nerves.
We are covered up with piping students both here and in the U.K. (the local piping camp in the summer in N.C. has a waiting list). They just are the wrong color (or religion).
