Why are extra characters still $3?

[Betelgeuzah]

I think numbers will show the value of charging $3 per character. I don't know of anyone planning to add many characters at that price.

Hell, I consider most vanity services way overpriced for any game. But some people still pay it up so I guess it's worth it to offer them.

I'm not saying that it's okay for SE to do this, all I'm saying is that everyone does it in some form or another (mostly for vanity stuff) and SE is not some exception here. It's a plague for the whole industry and to act like only SE does this sort of thing is silly.
