There are no principles involved when companies advocate for or against things. Companies will always amorally argue for whatever makes them more money. They are entirely capable of arguing two opposing viewpoints if in one context viewpoint A makes them money and in another context opposite-viewpoint B makes them money. Being consistent, either logically, morally, ethically, or in principle, is not necessary.
"Copyright is good and necessary when it makes us money, and copyright is bad and wrong when it doesn't make us money" is a mundane and totally expected opinion coming from a corporation.
