What Have They Got To Hide

In this case, it's the Federal Aviation Administration, which has a proposed rule to block public access to raw bird strike data:

The FAA says requests for data from the public "have typically been for specific data fields, individual airports or detailed portions of the database" and that responses from the agency "have addressed each request individually and adequately".

However, the agency cautions public analysis of bits and pieces of the data could lead to inaccurate portrayals of airports and airlines, which could have a negative impact on their participation in reporting bird strikes.

So, they are saying that think that ordinary people are too stupid to understand the data.

More likely, they are covering something up, like certain airports being having a lot more problems with bird strikes, and the FAA, which is tasked with both regulating and promoting aviation, finds this information inconvenient.
