One notable difference between meetings and lectures is the variance in skill level. In a lecture, it is reasonable to expect that if one student didn't understand something, he was not alone. A junior (or newcomer to a project) in a meeting, however, is a different story. That's a relevant distinction for deciding whether to write down your question for later, or speak up.

When a team hires a new person, they expect a lot of things to slow down for awhile as they explain things to that new person. This is the cost of onboarding. You pay the short term cost for the long term benefit. It is not fair to the new person or good for the team to refuse to invest in onboarding.
