Every piece called out here is clearly labeled "opinion" - did they even read the normal news and analysis sections? Countless newspapers and outlets and actual scientific journals have opinion/editorial sections that are generally very well firewalled from the factual content. You could collect the worst hot takes from a few years of nearly any site with a dedicated opinion page and pretend that it has gone downhill…
So, yeah, I agree that the standards are lower in these sections. I question if they are non existent.
