Why have recent SNS projects failed to launch

We should really think deeply, why the recent SNS projects are launching failure?
Does it mean that the SNS model has failed

The model hasn’t failed it’s that the projects in this place consider investors funds as donations. They don’t care about how to make the product profitable nor about liquidity concerns. There’s only a few good SNS projects the rest have done nothing for liquidity nor for their investors. Why would I invest in an SNS if they dont care about be, my funds, or profitability? SNS should be renamed charity dao if that is the case
