Admittedly, the talking heads of recent times seem to have taken the gloom part to ridiculous lengths. A more reasoned approach would be preferable, but then many of the talking hairdos of US (and probably European) TV would be unemployed.
The newspapers concerned here are not from eurozone countries. Preaching the demise of the euro is not bad news, doom and gloom from their point of view and that of their reading public. If they were trying to sell their publications on the doom and gloom ticket, they'd be talking about the decline of the US dollar and dollar-based GBP.
