I follow Blender on Mastodon and, about a month ago, they started this campaign to see if they could double the amount of donations (from approximately 1% of users to 2% of users), and it's been decently successful so far just by putting "Can you donate?" banners in more places (and posting memes about donating on their social media).

Here's a short video they put out about it: https://www.youtube.com/watch?v=-v7Uhoot4Qg

I think the funding campaign only lasts a month, so it's probably about over (though donations are always accepted, this is just a brief social media campaign to increase development funds for FY2025).
