You, as an individual, can also deploy several redirection techniques to shut those people down in either virtual meetings or in-person meetings.
Tacit approval is either given by non-verbal acknowledgement (looking at them), vocalized agreement, e.g. "uhuh", "yeah", "and then what happened?", or by silence.
I have an internal count that I do when someone starts talking and I become conscious of the interlocutor: "Hey, I need to interject, you raise a valid point about X but I have a question around it, <name of other participant>, what do you think of <completely unrelated subject>?"
And you repeat the "Hey, I need to interject,hey, I have a question, Hey, I need to interject" until the other person stops long enough.
Some days, you just have to be firm and get into the conversation.
You can also just butt in with "Hey, that's interesting but it sounds like we are lost in the technical weeds, could we please take this offline or move it to a different meeting?" If the person running the meeting doesn't pick up on that, they shouldn't be running the meeting.
I also like to drop in "Hey, I have to cut this short, I've got another meeting I need to run too, can we move this along?"
People are very unaware when talking on the phone or in a video meeting. Like literally they become deaf. After three or four attempts of interjecting in a very short period of time of just 15 seconds or so, if the person isn't listening, I've just started talking directly to the meeting running directly over them and saying "we need to move on. Can you mute him?" It might be considered rude, but it's what everyone is thinking.
