Most of what you said has been discussed in this forum but I know Eva Kiss doesn't visit these forum so I'd like to know how similar the discussions are on the discord/patron side of the community. My assumption is that people will be more amicable and understanding of her vision on those spaces
I lurk on the Discord now and then. My impression is that EvaKiss occasionally reads the Discord, but usually doesn't get involved with the discussions. The closest the Discord people usually get is interacting with someone who has a direct line of communication to her (bug-tester, etc.).
She occasionally interacts more directly with Patreon fans, but the Patreon blog post style doesn't really allow for discussions like a forum.
To answer your question, the tone is less negative on Discord/Patreon, for better or worse. Better because many complaints are just not helpful, but worse because any actual constructive feedback is less likely to be heard. I'll guess that the less negativity is due to (1) the people on Discord/Patreon buying into Eva's process (literally), so they may feel less need to complain, (2) some social pressure on those forums to not complain as much, especially on Discord with moderators being active contributors in the conversation, and (3) size. There's about 28,000 people active on F95 as I post this. There's a little over 1,100 on the Discord, and I think only a fraction of those are able to access all of the topic sections. There's a lot more opportunity for negativity with larger groups.
P.S. (4) this is a... unique forum. I can't imagine that every single scallywag pirate of such questionable treasure are warm, empathetic, altruistic folk. A lot more opportunity for freedom of expression, which cuts both ways.
