I think you're being way too charitable with Vercel's CEO. I don't doubt he came up with some way to justify to himself that what Israel is doing is completely necessary and reasonable. But I doubt you can get access to a press conference with Benyamin Netanyahu, then get close enough to shake his hand and take a selfie, then post the photo on social media with a tagline of the likes of "eternal glory to Israel" while having no idea of what is actually happening there. Either he's really that clueless about the world (in which case, how can he be CEO?), or he knows about the genocide and fully supports it.
