It is really not difficult to understand. I am a consumer. I have concluded that since I cannot use G lenses on my favorite analog cameras, G lenses are bad for me. Therefore, I will vote with my wallet. I will avoid buying G lenses and I will express my opinion on the Analog Forum.
Optically most of the ones I've used are very good if a little lacking in character, I believe 'modern' looking is the term. I sold all of the ones I had recently as I can't use them on my mirrorless Fujifilm or old film gear.
