What was the most popular name they rejected?

The Register article [1] says that it was Sneedacity, apparently a Simpsons reference.

This is, I think it's fair to say, a worse name than the one which was chosen.

Also, according to the 4chan thread I saw, short for "special needs".

That’s like when they said GamerGate was about journalistic ethics: a transparent lie to elicit sympathy. It doesn’t even make sense: what would that mean in this context? It’s not like they forked it because they were concerned about accessibility.

As you can tell from the cartoon and organization name, it’s a 4chan meme based on a Simpsons episode:
