Nothing nefarious here, just folks trying to help. One person was going off the release notes and said "nothing changed". Another person realized a change they made did affect NFS but they forgot to list it in the release notes.
Diagnostics are a critical part of the troubleshooting process. We ask for them because it helps understand what the problem is so we can reproduce it. We don't have time to play 20 questions to get the right details, if someone refuses to provide diagnostics then it often means their issue can't be resolved until someone else has the same issue and provides them, looks like that is what happened here.
BTW, much of Unraid is available in our public repo:

You can match up commit dates with the 6.12.1 release to see the exact changes if you are interested.
