Yes, he changed his mind after having too much trouble with ElGamal, according to a Wikipedian editor in 2004 who claimed to have worked for him (Jon Callas?). Neither ElGamal nor Elgamal is wrong per se but Elgamal better reflects his current wishes to the best of my knowledge, so while I won't edit anything to change ElGamal to Elgamal, I write Elgamal myself.

Here is an example where it is correct to say ‘Aes’: crypto.stackexchange.com/q/75230. The fact that this is in a quotation makes it unlikely to be detected by any sort of automated process of applying the proposed changes.

The votes are tied but so far nobody has written a reason why the attack tag is helpful for categorization.

Any rules you set down here should be justified not by your say-so but by reference to consistent usage in the cryptography literature. Where the usage is not consistent, these rules are not helpful. For example, Taher Elgamal does not write his name as ElGamal. One can make the case for Elgamal or for ElGamal by reference to existing literature, but you are overreaching by setting down a rigid rule here.
