Sounds legit, and I thought what FOSS project I love and OpenWrt is indeed among those projects, so you might want to check this:
1 - intro to what this fund is: [https://youtu.be/re1WbxqaJqs?si=PVV4Fap8LjwXCRTA](Linux and FOSS - A New Fund to help Struggling Projects.)
2 - check the links under the video
3 - if OpenWrt is good with finances and doesn't need financial support or for some reason you dislike this - please, excuse me and you can remove the topic.
I hope this is helpful.
