Abandon Digital at your own peril
What the article in reference fails in is to acknowledge the transformed nature with which people consume/purchase content in today's market. If market returns to a reliance on analogue then they'll find people will continue to seek digital methods to get the content they desire, and all that's going to do is to see an increase in the number of companies winging that piracy is baaad and their sales keep dropping.
Many companies were so slow to adapt from analogue to digital models, many still don't understand it properly but companies have come a long way and many are reporting profits now, even if they didn't rival analogue profits.
For years the artists, the producers and the creators have been upset at the likes of Time Warner milking most of their profits from their own production as it's gone to feed the pockets of the CEO of companies like these and their executives, digital doesn't allow for that, so it's in no way surprising that they'd prefer to hang on to the methods that kept their ability to buy million dollar yachts and multi million dollar mansions. It also puts more power back into the hands of the creators too.
