The reason SpaceX banned it is because of legal reasons: they can't export their tech. When children are involved, there are very similar legal concerns: they can't export the data associated with the children, aka: the video feed. I think both bans of Zoom are reasonable.

Why would schools need to export video feeds?

Right now it's been proven zoom lied about some parts of it's tech, particularly the end to end encryption part, so the state probably sees it as a legal risk if anything were to accidentally get out or get hacked.
