On the Fireside Fedi interview with Jerry ( the admin of Infosec.Exchange Mastodon instance ) a scary truth was suddenly revealed ( on 34:11 ): Just to keep the instance up and running he needs to spend up to $5000 a month, pretty much out of his pocket. Donations to the instance barely cover any of that. And if he will ask people to pay to use it, they will, rightfully so, switch to a different instance.
This is separate from the Communick Collective. The collective is just a way for people to support creators directly. My pledge of 20% is for the underlying projects. I am pledging to donate 20% of the profits to Mastodon, Lemmy, Matrix Foundation, Funkwhale, GoToSocial, Pixelfed, etc.
For that to happen Communick needs first to turn a profit, though.
