IMO there is no advantage to having "community" notes taken of a meeting: I take my own notes about decisions made in the meeting that I care about, and items I need to take care of. Therefore, every meeting I'm in has notes taken, though no one else is even aware (unless they are taking their own, which I assume many are). I think this is relatively common (since I can't see how one can function in most knowledge work without some version of this) so I would assume that you probably are in meetings where notes are taken, even if you never see them.
This is moving the goal posts, though, and you know it.
In a meeting with "notes taken", there is someone tasked with doing so in an official manner usually decided by the person coordinating the meeting. It is also typically known by the meeting attendees that this is the case. Those notes are usually made available after the fact in whatever form is normal for that company. In Zoom type meetings, we all get the "recording" notice during the meeting.
What individuals do is not the point of this thread. However, we've seen plenty of examples of where individuals do record on their own devices meetings which were meant to be private but leaked later. Again, that is out of scope for the general purpose of this. Again, you know this. Or at least, you should
Sorry, wasn't trying to move any goalposts: you're replying to my first comment in the thread. I've never experienced the situation you describe, and literally didn't know that this was a practice. I've seen formal meetings run by Robert's Rules, which have a secretary keeping "minutes", which are a subtly different thing and are generally not useful for anything other than official purposes.
I've also seen meetings where some enterprising project manager says they will "make notes available". Sometimes they even do this, but even when they do, the notes are useless for everyone who isn't them -- they've just distributed their personal notes in the hopes that somehow they would be useful to others in the meeting, which of course they aren't.
