Author behaving badly or Wesley's feathers easily ruffled?

I follow a certain person on Twitter and he recently put out his first book. I volunteered to be on the launch team. I read the book, thought it wasn't bad, posted a (what I thought was a fair, maybe too nice) review and put it on my blog.

Today, I saw that he had tweeted a picture and a strange sounding tweet so I investigated.

This is the tweet in it's entirety (I was trying to photoshop it into the blog and black out his name and I was having computer issues. If you would like to see the quote to make sure I'm not making something up I can screen shot it for you).

"Thanks for taking the time to read my book Kaitlyn. I'll work harder on flow next time. Probably still at McDonald's"

The picture that accompanied this tweet was a section of a book review posted on amazon. The text of which is below:

"However, the book as a whole felt very disjointed to me. Within each chapter, there are section breaks. these section breaks always include a time, a location, and a paragraph about "pre-thoughts." In other words, it's like reading a journal of what (author name redacted by Wesley) was thinking before writing each section. It sounds cool, but it was extremely confusing. It broke up a train of thought and made each section stand alone instead of flow together. I wanted to like it, but I didn't care to read about how he was writing at McDonald's but hadn't been there in months and will anyone like this book, oh wait, maybe he should start writing but he doesn't want to write anymore. <-- example"

My first reaction was, well that sounds kind of petty and crappy of him, but maybe I'm just reading it that way and he doesn't mean it like that. He does start by thanking her. But then, follow up tweet.

"As a first time author I reserve the right to be passive aggressive."

Couple things:

Why would you use the person's name? The photo that accompanied the tweet didn't show the reviewers name. I feel like it's being kind of unreasonably/unnecessarily petty to call a person out because they said there was something that they didn't like about your book. (To be fair, this also annoyed ME about the book). It feels a little book reviewer shamming-y to me
and that gives me the icks. 

The author can obviously react to criticisms how he sees fit, but is being passive aggressive the best course of action here? Why the follow up tweet? (Not everything that pops into our brains needs to be shared, it's a hard concept for people, me included. Twitter doesn't really help with that.)

So much of this book talks about accepting people, and grace, and forgiveness, and "everyone has quirks and weirdness and that's what makes you great" and then I feel like this is very lash out. Or maybe just a joke that fell flat? Why not just default to kindness?

Maybe just "Thanks for taking the time to review my book. I'll probably still write the next one from McDonald's." Or something?

Am I being weird about this? Is this actually funny and I'm being offended by literally nothing? Let me know your take, because I feel like this is crappy of him but maybe I'm just put off by it because I was apart of this person's book launch.
