Twitter employees planning to quit their jobs over Elon Musk’s purchase of the largest share in the company need not apply to Substack.

Substack, an online publishing platform for writers, announced Tuesday it is seeking to hire a data analyst and several product managers and systems engineers, among other positions. But Twitter employees thinking about quitting their jobs “because [they’re] worried about Elon Musk pushing for less regulated speech” were told “do not come work here” by Vice President of Communications Lulu Cheng Meservey.
