SD Cards have computers inside of them. Security conscious users will be really worried using a blob for their stuff.

Are there any open source sd card firmwares?

Would be an interesting project, I have no idea how you could reprogram them though.

Some manufacturers have proprietary undocumented APIs that allow the host to upgrade the firmware in the card, but I’m not sure every maker does, and very sure most wouldn’t bother to update their firmware unless some horrendous issue came up.
Hard drives, USB sticks and SSDs too...
