I don’t think optimism vs pessimism is the right frame here. I’m very optimistic that pretty much everyone who pledges to any project via Snowdrift.coop will be someone with overall good intentions and who cares about the kinds of issues Snowdrift.coop was created to address. However, that’s not the key point here.
The point is that for Snowdrift.coop to make a difference it has to get off the ground and quickly become sustainable. People who come to Snowdrift.coop to support Project X that they care about will mostly be busy, distracted people like we all are, and Snowdrift.coop will be something new and unfamiliar to them.
I’m very optimistic that they will in principle want Snowdrift.coop to get the support it needs to continue functioning. However, there is a big cognitive and motivational distance between that and actually pledging to Snowdrift.coop.
If we allow projects to support Snowdrift.coop with whatever portion of their donations they choose (from 0% up), as itch.io does (see their blog post I linked to above) - as well as allowing anyone to pledge to Snowdrift.coop directly - I think that will meet everyone’s needs much better. People who learn about Snowdrift.coop and think it is really important and want to support it directly will still be able to do so. People who mainly just want to support Project X will be able to do that while automatically helping to sustain Snowdrift.coop to whatever extent Project X has decided Project X feels good about. And Project X will be have some power to help ensure Snowdrift.coop succeeds and continues to exist, rather than just having to hope that a big enough crowd of dedicated Snowdrift.coop fans forms to make that possible. Over time, to the extent that such a crowd does arise, and Snowdrift.coop really doesn’t need more funding than that crowd provides, it would be perfectly possible to reduce the default or suggested project contribution to Snowdrift.coop, even down to 0%.
