If those paid members aren't canceling, then maybe they're just not as butthurt about the update as you are. At the very least if they're critical about the update, they don't believe the criticisms are worth canceling over. Just an idea...
Despite the pages of crying on this thread, if the number paid subscribers remains in the multiple thousands, then the support on Patreon still far outnumbers the complaints on F95. That's not an indication of a problem... That's simply an indication that they can appreciate this VN even when you can't. It's still one of the top tier VNs despite your feelings. That's why it earns so much support.
