@FinchHaven It's explained on the article for the @Mastodon Annual Report for 2023. They have more data for the 2023 report than before and have also already started on the 2024 report.
The income is from patreon donations and one large corporate donation of $100,000 from Sujitech - a Japanese tech company.
It is all in the report which is accessible from the linked article.
へええ、MastodonにはjpやPawooなどを運営しているSujitechから大きな額の寄付があるのか(わざわざ別に言及するほどのレベルということか)
