And also not a lot of companies want to be associated with Covid-19 content.
You can't bury your head in the sand about this. Frankly, in comparison to this, almost nothing else is even worth mentioning. And anyway, it's not like there's sports to cover. Almost nothing else is going on besides the pandemic because everything was shuttered to fight the pandemic and even that is just barely enough.
At a certain point it becomes information overload/noise and people just tune out, myself included.
As it is now it's just overwhelming to look at any news.
It doesn't help their case that they massively publicise things like panic buying, knowingly causing the issue to spread.
And I don't think many companies are concerned appearing next to a Covid article, they're ubiquitous anyway. They just need to save money and online marketing can be cut within minutes.
