The 'mission statement' seems to suggest that the platform is adding an extra layer to commoditise the celebrity/personality and their lifestyle, by solidifying ephemeral contact built via other channels, into a direct-to-consumer approach, who then become investors and/or stockholders? There is also an overlap on features of other established networks, so it will be not be easy to carve out a niche.
Nonetheless, it seems like a warped enough concept to achieve some success, despite contributing further towards the erosion of society and burning or reviving the careers of some wannabe/z-list celebs, amongst others.
It wouldn't surprise me if an established NSFW platform adopted this feature as well, drawing away the people with those interests. And as the app developers have this rule from the beginning at least they're spared the backlash that Tumblr experienced when they banned nude content out of nowhere, paired with a content filter biased towards false positives.
I kind of agree with your sentiment on this and I believe it will end up, sooner or later, into what you described.
