Isn't Sky News pretty heavily subsidised by the wider Sky network? That's why threatening to divest it = threatening to close it. Selling it on as a loss-making concern isn't a great business opportunity is it
The idea is
force the regulators' hands
to making a decision. The Murdoch clan may still be reeling over their failed attempt at taking over Australia's Network Ten (as well as stopping the successful CBS bid), the Fox News brand and all related allegations regarding Fox News talent possibly derailing the full Fox takeover bid and a possible Disney buyout of 21CF properties that exclude the broadcast network, news and sports divisions. This "forcing someone's hands" bit also comes at an interesting time: In New York City, two local news websites DNAInfo and Gothamist, were shut down by the owner, Joe Ricketts --a donor to the Trump campaign and part of the family who owns the Chicago Cubs baseball organisation--- due to staff agreeing to unionise. Ricketts has said both publicly and privately that should the staff unionise, he will shut the sites down (including its sister sites who did not unionise) The staff, colloquially called "DNAist" voted to unionise and six days later, all sites were shut down, citing DNAist "not been sufficient to support the expenses". For a period of close to a week, all sites had their material taken down and replaced with a message from the owner that read in part:
But DNAinfo is, at the end of the day, a business, and businesses need to be economically successful if they are to endure. And while we made important progress toward building DNAinfo into a successful business, in the end, that progress hasn't been sufficient to support the tremendous effort and expense needed to produce the type of journalism on which the company was founded
All stories published prior to the closing down were returned, but with a link to the owner's statement http://assets.dnainfo.com/message.html
In short, it's all about forcing someone's hand and attempting to corner them into making a decision. It's not so much a business opportunity, but an old-fashioned shakedown.
