Fediverse is open source and decentralized, so any for-profit model could leverage it without asking for anyone’s permission. There are already for-profit companies that build and maintain apps to access Fediverse platforms. Meta Threads and Tumblr are both integrating into ActivityPub as their own hosts. I imagine in a future where Fediverse grows rampantly, the hosts with the best overall user experience will be for-profit. We live in a world of global capitalism, good things cost money most of the time.
Protocols can be developed and then shared without cost except for the upfront development costs. Hosting a continuous service requires regular income, meaning for profit models will always out-resource non-profit models of hosting. Especially if a platform is looking at hosting more than just text and compressed images. Why do you think Pixelfed’s main host only allows uploads of up to 15MB?
