He spent the night insulting them and they told him that no one cared, that's not rude that's response in kind.
It might be odd seeing defensiveness from a marketing account, but it's not unexpected. They're going for hip and cool and it's neither to let a rando insult you.

That's not true. Asking, in one tweet, if it's "narcissistically gratifying" for MW to be the "chill dictionary" may be insulting, but not needlessly so, as I think that's the central point he's trying to make. Overall though, they are a meandering, somewhat pointless series of tweets, aimed at a company, and not an individual.
Stating that "No one cares how you feel." is needlessly insulting and isn't attempting to make any point. It's also directed at an individual, and not a large company, so it's always going to be perceived as more cutting.
That "No one cares how you feel." is, apparently, an expression commonly used in English teaching doesn't excuse it: the author, and the vast majority of Tweeters didn't get the reference.
A guy writes about his brush with fame when MW was rude to him on Twitter.
