ok, apologies to @eff
I made a post angry that the only name I could put on the donation form was the one it would (probably) use when it ran the card. I'm a little sensitive about this subject after the situation with Microsoft yesterday.
When I tried submitting the form without my deadname on it, the charge went through, so I was wrong. I deleted the original thread. My only feedback would be that it could be clearer that the name entered does not need to be your billing name.
Support the EFF, they're wonderful. https://www.eff.org/vv
