Newspaper endorsements are just another corporate press release

At the end of an election campaign, a newspaper's endorsement used to mean something. It used to be taken as considered and authoritative judgement by the newspaper's editorial office about that particular election campaign and that particular set of candidates.
Now? Its just another corporate press release.
The Globe and Mail started it off last week in a ridiculous editorial that endorsed the Harper Cons, without Harper, and it was widely mocked on twitter.
Then all of the Postmedia brand newspapers in Canada ran so-called "editorials" written by their corporate office supporting the Harper Cons, and the Edmonton Journal editor described it as the "right" of the Postmedia owners to do this.
Now the National Post has lost their editorial board chair, Andrew Coyne over their refusal to let Coyne endorse the party he wanted to endorse. Their corporate endorsement, of course, went to the Harper Cons.
