Yeah totally.. people no longer buying printed newspapers obviously had nothing to do with it.
My brother used to be a newspaper reporter and then editor in the US.
His take was that the early pain came from Craigslist eating their classified ad sales.
The Manchester Guardian has always been lefty. That's not a new thing.
Its right wing broadsheet counterpart -- the telegraph - just filed for bankruptcy. So I don't think there's any counterfactual to support your 'arugment'.
TBF while I think the Telegraph is flying into extremely bad headwinds by chasing a literally dying audience, it's bankruptcy is due to the ongoing feud between the family that owns it and them trying to starve each other of funds by pulling cash out of the parent company rather than the business of that newspaper itself.
