While I agree with you, it is ultimately the developers decision to engage in Communities he/she deems beneficial.So it is good that Shine is still alive and the project is running. On the other hand, I do not understand the attack on the F95 (moreover, a specific explanation is missing). What is special happening on F95? What Shine doesn't like? People discuss and yes, there is a little more freedom and the world is not always nice place and not all the comments are nice. With that one has to learn to live and be able to filter and ignore some nasty comments.
And I'll be skeptical. I've seen this behavior many times. All sites, social media, platforms killed, F95 ABANDONED tag, but Discord Bubble (and "heroism") goes on. Promises, teasing, strong words, everything is wrong, especially on F95.. and this never goes anywhere. But maybe Shine surprises.
I hope I'm wrong.
Although I would also argue that even with the weirdness and toxicity going on on F95, it probably is still the by far best platform to market an H-Game and build a Community for it in the English speaking part of the Internet.
Still toxicity can and will tank the motivation of content creators, it is human nature and some people have a harder time filtering comments than others. So, taking a break from social media can sometimes do wonders for the development process. As you said, we will have to see how Shine proceeds further.
