My main concern as an app owner is will the % change? I dont think many ppl will be interested in making apps for MP for any less of a %.
The auction process is still on-going, so I think it'll make sense to wait until we have a winner announced instead of speculating. That said, app owners are the life-blood of MP, so I doubt anyone is going to buy the app just to squeeze them.
Yeah, I don't foresee this being an issue, either. It wouldn't make sense for someone to start alienating their userbase, as that would just result in a crash of the system and loss of investment money.
