No, I am not wrong. Baker changed his mind in 2019. 15 years AFTER writing Races of Eberron (2004), which stated the GM should decide, and 2 factions freed the warforged NOT because they have souls, but because they could think.
Baker changed his mind, fair. Now we know what he thinks, but to those who only buy the books, a blog from Gygax, Baker, Arneson, Tweet, Mearls, etc is useless because it should have been in the books to begin with. Making excuses for a poorly written book, just means a bad designer.
