The line for "imminent" and "likely" is subject to argument, sure, but the point is that, if you want to say something which will lead directly to the attempt to overthrow the government, you can be censored.
Upon further thought, something occurred to me. I am imagining a TV channel similar to the ones my area is littered with. I'll hold my nose and argue for their protection.
But because we're talking about Israel, I could well imagine some content, that would go unnoticed here, but qualify as incitement to destroy the country. I'm talking about the religionists who are always on about The End Times, and how reestablishing Israel, rebuilding the Temple, and converting Jews to Christianity(so they don't burn in Hell). I could easily see some of the more bizarre religious teachings I hear (a lot) construed as "Destroy Israel, so Jesus can return in Glory". And the people promulgating such beliefs aiming their messages at impressionable youngsters, because adults are usually immune to such nonsense.
So yeah, I could see some content qualifying as "Overthrowing the government for God". That's not what I was thinking about earlier, but I could see it happening. I could understand threatening their license if they did that.
