I'm pretty sure that everyone is aware that an article from jacobin has these biases. Perhaps it is notable because you're so frequently exposed only to billionare and corporate biases.
Nothing wrong with stating the sources up front. They are clearly pro-labour and pro-union. It helps to know where the authors stand. Would you rather the authors were buried under seven layers of shell companies?
i never heard of Jacobin until today. I just thought it was interesting that they were open and clear about the authors, more so than is obvious in usual journalism online.
what i found interesting is that the authors are so clearly described, at the end of the article, which contrasts with most of the news sorts of articles i see online.
