Contrasting the tone of innocence the larger publications use around these institutions feels perfectly within a journalistic mandate.
For new and under-reported (or otherwise downplayed) stories, I think it's understandable and maybe even good. But when every single story has a breathless, scandalized headline, it gets exhausting fast, and it's hard for me to know what to pay attention to.
I remember last year 404 put out a clickbait-y story about the shitty "covert" websites that the CIA used to communicate with spies they'd recruited in Iran, even though it was old news at that point. If you only read the headline (as many people do...) you'd think it was a startling new development.
Nobody is disputing that it is a legitimate choice. It is also legitimately off-putting.
If their audience is into it though, good for them.
