So how is Kbin going to cover its operating costs? If a fediverse server must survive on donations, it seems like donating should be built into the user experience. For example, there could be a Kbin Gold similar to Reddit Gold.
I remember years ago when Reddit Gold first became a thing there was a progress bar on the site indicating how much of their daily server costs had been covered by Reddit Gold. Something like that might be useful.
Who's going to be paid for the ongoing maintenance of the software? Who's going to pay for the servers the software's run on? A decentralized architecture doesn't remove the operating costs of a large scale social media site. As the article alludes to, it might even increase operating costs.
To be honest, I'm not interested in small, niche communities. I want the fediverse to grow into something that can rival social media giants like Reddit, and Twitter. How a site is monetized is as key of a feature as anything else, because without monetization, a site is doomed.
