Also, Wikipedia has donation drives, non-profit status and a highly controversial history of how it spends the funds they collect. Lots of high quality contributors already left because they were not recognized in any way and ended up feeling exploited.
I do not agree that just calling for moderators and volunteers means a business is unsustainable.
Perhaps it does in this case - I don't know enough about Hachyderm to know for sure. But it's possible that the roles of moderators and volunteers at Hachyderm might not be (or could be made not to be) so terrible, in which case relying on free labour is a proven and sustainable business model (for some businesses anyway).
Also worth noting that a "highly controversial history of how it spends the funds they collect" at Wikipedia is not directly correlated to Wikipedia's sustainability at all - the history shows otherwise.
The problem is that example you gave (Wikipedia) is not a business.
> I don't know enough about Hachyderm to know for sure.
My point is not about Hachyderm in the particular. Like I said in the first comment, I think they have what it takes to continue operating and serving their community for the longer term.
My issue is with the overall ecosystem and the expectations of the people coming in from "traditional social media sites". If we want to provide an ethical alternative to Twitter/Facebook/Instagram/WhatsApp, we need to find a way to serve hundreds of millions of users. How are these people going to be spread around the instances? For context, we would need ~15000 Hachyderms to replace Twitter and ~60000 pixelfeds to replace Instagram. Are they all going to be dependent on volunteers? Are all these instances be operated by highly paid professionals from SV who can sink a few hundred dollars every month? Or are they going to go to appeal to "your donation is very important to us" and expect that a few generous souls make up for the free-riders? Or are they all going to eventually cave in, start treating it as a business and start charging from their users something that can pay actual salaries for everyone involved?
You then give that person the ability to delete stuff that violates the rules. Repeat with giving the highest trust / highest use users that power until you stop seeing garbage get through.
It is not at all any more stressful than being any other user, but instead of occasionally seeing garbage posted and being disgruntled that it's there, they can just delete it.
That said, although /. lives on, it is only a shadow of its former self AFAIK. Perhaps that indicates unsustainability.
This is why they are quitting in droves, and this is why I stopped donating to them.
