While I understand the content on medium is different per author, I associate it with poor quality content. It may pop up in search results, but I actively avoid the results because of the association. Point being, the exposure you get may not be the type you want.
Also don't forget your content will be subject to the user experience medium decides to provide. I think it's already subpar with it being full of popups and prompts to register and pay for an account, but consider how companies constantly enshittfy. You are giving away the control of how you are represented.
I just hope that 1 IP they're so bent over turns out to be a CGNAT IP.
