Why? It is not like there is serious privacy violation in telling that altimeter broke, and this makes the data much less reliable. Not saying the data is fake for sure, but I have came across enough haters of 5g, and I am pretty sure someone could post fake entries just to scare people.
ASRS (https://asrs.arc.nasa.gov/) is how both private and commercial (including ATP) pilots can anonymously and non-punitively share safety or otherwise concerning events.
The goal is data collection to assess and prevent incidents. NASA's intake on the reports are not anonymous, but their public reports are. NASA functions as the filter between pilots and the FAA/NTSB.
Because the airline industry isn't too keen on pilots reporting safety issues. Fear of retaliation would stifle reporting if anonymity could not be ensured. This has nothing to do with 5G.
The airline industry is very keen on pilots reporting safety incidents. Over the years it has moved more and more towards being a no-blame environment: as long as an incident is immediately reported and wasn't due to gross negligence, you will not be punished.
If pilots are not afraid to report incidents, they will report them more often. This in turn means that hidden issues are more easily discovered, which in turn could save lives.
