I think this reinforces the fact that this is nothing more than Facebook literally vandalizing their own service in a petulant display of mock martyrdom, claiming that this is necessary for their business.
How on earth could it possibly be a viable business decision to say that the students at McMaster University and the journalism they're producing are in any way a significant threat to their bottom line, such that they have to withdraw their facilities from them?
I think it's in the petulance, in the sheer scale of their decision and in the lack of care that they've taken with it that you can see precisely what it is they're up to. Thank you for highlighting that.
