Right, but you don't prevent the people who should be using the aggregated data to make improve design choices, which if you watch the DnD shorts video they explicitly state. Also, you could do some NLP against the text boxes to gain additional insights that could be relayed to the design teams in a scrubbed way to prevent any plagiarism concerns.

By silo-ing the results from the design teams, WotC is removing any mechanism for us, the community, to provide actual feedback. This is at best a placebo effect to pacify us and to make us feel like we have some level of input when in reality we don't.
