This week, Matt Comyn wasn’t pulling any punches. The Commonwealth Bank chief executive used his appearance at The Australian Financial Review Business Summit to attack the market power of Apple and other digital platforms.

“One of the things that I find extraordinary is the lack of scrutiny, across some of the tech companies, in particular, which have large businesses in Australia,” Comyn said. It was a comment that came in an environment where the major banks – and more recently, supermarket chains – have been under significant political pressure for their big profits.
