It may also be relevant to note how Merriam-Webster's editors decide what to put in the dictionary

To be included in a Merriam-Webster dictionary, a word must be used in a substantial number of citations that come from a wide range of publications over a considerable period of time. Specifically, the word must have enough citations to allow accurate judgments about its establishment, currency, and meaning.
This means there isn't a magic judge of all things arbitrarily deciding to "make changes to the English language". MW adds words to the dictionary when the words have enough staying power, demonstrated by both recent and extended widespread use from a variety of sources.

They're not changing our language; they're documenting how our language naturally changes with society.
