Is there a sufficient reason for covering their faces?

I would have thought there would be ample reason for them not to be identified. We live in a cyber-security state. Once recognised by the spooks (facial recognition) and others (Friends of Israel perhaps) they are liable to be corralled and neutralised and suffer consequences of standing up to genocide. They stand more chance if they are incognito, as much as possible. What's the point of being a target for these malign forces?
