I don’t know. People on this forum are all GF owners (at least that’s my understanding), who have spent a pretty buck for the privilege. So I don’t think your ‘couch warrior abuse’ is a real threat in a closed community like this one.
Expectations should be managed though. My experience is that it is effective when the company offers a list of features that perhaps they have already evaluated as being viable. The voting is about information for the company to prioritise resources, not to please everybody and their dog. A ‘feature wishlist’ is also important but it’s something else.
