To be honest, I don't think there's anything you/they can do, other than heavily rebrand or shut the project down. I find the entire premise of a commercial product and company branding themselves in support of (or in opposition to) a political situation morally deplorable. It is taking advantage of a current conflict and people's political leanings for their own financial gain. It doesn't matter if the people behind it are directly involved in the conflict or not—it's a cheap marketing ploy.
It would be no different if the "Big Tech AI" companies they criticize promoted their products in support of Israel with Jewish-friendly branding. Biases are one thing, but basing your entire product on them is entirely different. It is tasteless regardless of which side does it.
This is the first I've heard of it, but your Tech for Palestine endeavour gives off similar vibes. I'm sure you mean well, but this is not the way to help people going through a difficult time.
But then again, I'm just a rando on the internet. Good luck.
