Dictionaries don’t change anything; they are books. Word definitions are changed by, you guest it: People! What we want to know is this: WHO did this? Was it one person? Was it an editorial board? Whoever is was, they have Names. Where do they work? Where are they hiding? Inquiring minds want to know. Please tell us who you are, you sniveling cowards.
I’m coming to believe that online “reference” sources are open sourced, Wikipedia-style. Customized on an anonymous whim.
