I think it's self promotion in both cases. A lot of people who put out these articles on how bad their working conditions were seem to be trying to turn their woes into a z-list internet celebrity lifestyle. They want to turn the controversy from these 'leaving' articles and videos into a larger social media presence and montly Patreon bucks.
Look at that woman who got fired after complaining about the conditions at Yelp for example. She tried to turn the situation into a personal brand.
It's the internet version of people that try and become Z-list celebrities through reality TV shows.
