That's right. But I find that meeting organizers are reluctant to cancel instances of a meeting even when they don't have much to share, because they are unsure in advance if others on the meeting may have something to bring up.
I always send a "I am good to cancel today's meeting unless someone has something they would like to discuss." Takes no more effort than just cancelling.
I do that for internal meetings where the members are on the same team. But on meetings across teams or organizations, I've found things often get more socially complicated. Especially if the incentives for engagement are not aligned.
