Essentially, at best USCIS ignores the problems and denies it. At worst, they hide data and become more obscure. For example, when I filed I-751, I could look up processing timer per each individual service center and field office. Now when you go to https://egov.uscis.gov/processing-times/, you can only filter by "All service centers" and "All field offices". Essentially, the details are being hidden. I wonder if it's because of large differences. Some offices and service centers had 2+ year estimated time difference compared to others...
