There's only one primary owner of Medium, FAIK. https://en.wikipedia.org/wiki/Evan_Williams_(Internet_entrepreneur) No idea how involved/interested he/they are. My feeling is it's Jewish people at the company who personally feel anyone criticizing Israel instead of focusing on Hamas are antisemites, or just don't get it. Their whole life they've been lead to believe they're the good ones, the ones persecuted for centuries, etc. At least that's what I've been taught.
One of the favorite sayings of a Jewish friend of mine is , "The squeaky wheel gets greased." They are VERY squeaky (as you point out in your story).
However, I believe the tide is turning. Even they can't ignore the way Israel is literally bulldozing half of Gaza down to the dirt. Destroying people's homes without any due process, day in court, evidence. They can't ignore the starvation. The TikTok videos of settler thugs. Etc. ETc.
I've predicted in my stories that American Jews will eventually have to choose between Israel or Western liberal democratic values. Tragic it's come to this. I still can't believe what I'm experiencing.
