Yes and Mastodon itself is a registered non-profit organization. There’s a few people they’re able to pay to work on the projects, thanks to sponsors and donations. But there’s a lot more contributors (over 800). I think the people doing valuable work on FOSS projects have a lot of opportunity to work elsewhere if they feel like they’re being made to do things antithetical to their values. Not to mention the amount of noise they could make to expose the project and its shady goals, if that were the case. Things do work differently for FOSS projects than your average for-profit investor-driven project.
