Yes I read that article too when researching this - it seems to pop up in a number of places. But I'm not sure that's it - removal of music suspected of streaming fraud seems to have been going on for months, whereas this is a bunch of quite established artists having multiple entire albums removed overnight. It seems to have been something large happening over the last few days. I'm hoping it's something like a bunch of labels have been slow to renew their licensing deals or something, and the music will come back online. I can't imagine Martin Carthy's being accused of streaming fraud.
