Clay thank you for calling this out. This happens on Twitter a lot as well. Theft of Black intellectual property is widespread and happens across several mediums (No pun intended!). A lot of times it doesn’t even get called out, or if it does the platform rarely takes responsibility for its role in facilitating piracy and plagiarism.
I am sorry to hear that this has happened to you and look forward to Medium taking full responsibility for their harmful and underhanded publishing methods.
And Momentum should run you a reprint fee.
