It seems to me that the common rationale for getting rid of the fishing reports is that they want to protect our river ecosystems. I would back that sentiment 100%.
I am hoping that this isnt coming from a selfish place, where I don't want to share my sport, my spot or my fish with someone else because our rivers are already too busy.
If it is truly conservation that you are concerned with, then simply removing fishing reports will not come close to achieving your goal. People will still get the information via PM or some other site.
There are much better ways to be a steward for your favourite piece of water.
