We wouldn't want to feel married to a feature if it doesn't successfully drive revenue. If the FBA holder does not hold up his end of the bargain, which is driving transaction growth, shareholders and entrepreneurs will be inclined to circumvent, steal or compete with the feature.
Why is that a problem? Business ventures come and go all the time, it's only when they get subsidized, propped up or bailed out that artificial advantages and corruption of the market occurs, changing it from a free market to a coercive and manipulative one. If the private transfer feature fails for any reason and a competitor is willing to risk stepping in to compete the process may repeat with a new approach and new conditions. Or, the feature fails and disappears b/c it just isn't viable. That's the free market.
OnceUpon is taking on all of the risk so he is entitled to 100% of the benefit. That's NOT 100% of the fees collected, b/c 20% of those fees are overhead paid to the ecosystem, thus helping to sustain the ecosystem.
Furthermore, he is being highly generous by his willingness to sell his controlling interest in the FBA revenue stream to a 3rd party that will hopefully offer that revenue stream to the community.
That is the part of the plan which is the most foggy IMO, b/c until private transfers are implemented and the STEALTH FBA begins to produce revenue, nobody has any idea what value it represents, it sheer speculation. Moreover, it is a sticky matter to dictate to a buyer of a thing what they can or can't do with it after they own it. So what control OnceUp has over the revenue stream AFTER he sells it cannot be known, especially right now before the revenue stream exists.
Just for the sake of argument lets say private transfers are wildly successful and OnceUp sells his entire stake in the FBA revenue stream to a 3rd party that says they'll offer some of it to the public but that 3rd party changes their mind and decides to keep 100% of his proceeds (80% of the fees). That is their right to do, barring some license or contractual agreement with OnceUp to the contrary. In such a scenario there is nothing stopping someone else from offering a competing solution and trying to capture a portion of that lucrative revenue pie. If their "new and improved" private transfer feature has value, can be marketed effectively to capture a portion of the market and return proceeds to the community as OnceUp intended, it might succeed in capturing a significant portion of the market or applying enough pressure on the incumbent feature provider to start offering dividends.
Point is we can't be certain of what the future brings but denying an investor the rewards of his investment and expecting an entitlement to the upsides but not the downsides is totally contrary to the free market principles this ecosystem is built on.
