The SMH have always made it personal when it comes to Tony Mestrov.
Their conduct dates back to his days as the CEO of Greyhound Racing NSW and the "battles" GRNSW had with the SMH/The Age/ABC regarding the welfare of greyhounds in and around the greyhound racing industry.
They've never liked dealing with him even when he faced enormous pushback from Macquarie Street, the articles they wrote (only one journalist, Chris Barrett from memory, wrote a balanced article at the time) were always quite firm on their opinion of him and his tenure at GRNSW.
NewsCorp would usually take a more "pro-GRNSW" stance.
