Management can 'drill down' to get information on how specific teams responded.
One of the things they mentioned doing is using a statistical (differential privacy?) model to limit the depth, to prevent any specific persons responses being revealed unless it was shared with a substantial number of other responses.
Surprisingly difficult when you consider e.g. a team lead reading a statement like "of the 10 people in your team, one is highly dissatisfied with management" - they have personal knowledge of the situation and are going to know which person it is.
