Yes, but the point of all my suggestions is to make things automatic.

Besides the feedback to the organizer part, there could be all kinds of stats about the meeting, compare to the stats of e.g. a sports game. If you have a pool of sales reps, and you want to help them improve, you can compare the stats: on average you ask 2 questions per call, while the average rep asks 10, etc..

Don't get me wrong, there are a lot of nefarious use cases, but there are definitely positive ones as well.

I can see the use cases, but the nefarious ones kind of obscure this prospect.

Maybe the negatives could be mitigated by doing the automated analysis on the client and asking the users if they want to send the feedback, similarly to how crash reports for software are often done.

Yeah, that might be a good mitigation! It will never be perfect, but that's life ;)
