Buzzfeed has an investigative journalism arm[0] that its built over the last ~7 years. They were a 2018 Pulitzer finalist[1].
I assume their clickbait subsidizes their investigative journalism, a business model that gives me hope given the importance of investigative journalism. Unfortunately that hope is tempered by the recent round of layoffs.
