The main question is what behavior is being introduced. I haven't researched deeply, but apparently the add-on does nothing until the user opts-in on studies.
Nobody is concerned about that, in my opinion. I'm concerned someone will push malware through Mozilla into Firefox installations. Pushing addon installs should not be possible at all.

"Looking Glass is a collaboration between Mozilla and the makers of Mr. Robot to provide a shared world experience."
It doesn't matter who technically coded it. "Mr Robot marketing department" was obviously deciding about its existence, behavior and content -- if that description is true.
But looking at the source of the extension, I find the following URLs inside:
https://www.red-wheelbarrow.com/forkids/
https://red-wheelbarrow-stage.apps.nbcuni.com/forkids/activi...
So it seems it is some marketing, the question is which company now, and do they change?
An art director and copywriter sat in a room together over two days and came up with lots of different ideas to generate PR for Mr. Robot. They presented the ideas to a creative director, who went through the work and picked the one he felt was most suitable. They presented it to the client, who supported the idea.
There would have been some line of communication from the creative agency, whoever owns Mr Robot, a media/PR agency and Mozilla. The idea was bought by the client, had the agency liaise with media/PR, got in touch with Mozilla with an undisclosed donation and the add-on was coded.
Then some marketing people both in and outside of Mozilla push something that is probably not passing the same strict reviews.
It points to the organizational problem in Mozilla.
Re: "not sure": don't worry, some people do this not for the content but for the author, some lack reading comprehension and some just press the wrong button. Just vote yourself, and if you reply, say that you agree, don't mention the word you mentioned.
This looks like "let's give litte Perry and these marketing departments something to play, whatever, it's just an extension, who cares." So little Perry writes a description of the extension "MY REALITY IS JUST DIFFERENT FROM YOURS", the extension gets silently pushed to all the US users(!) (Firefox has support for that) who freak out, and the first response from somebody involved with that was "it was not supposed to be seen." You see, it was planned to keep the extension also "invisible" to the users -- Firefox has support that too! The extension was obviously not formally reviewed or formally tested, if the "invisibility" was the goal. Of course, it being "invisible" wouldn't be better. It's a misuse of the whole mechanism, compared to what Mozilla explained to the users. The mechanism was supposed to allow making "studies" from the behavior of the users who agree to take part in them. Instead, it was an attempt to a "viral ad" that was delivered to the whole Firefox using US population. There are multiple wrong decisions in this story.
Now I hope Mozilla does get the idea that the users do care.

BTW: the extension we all talk about here has exactly this site that is used for checking the headers hardcoded inside, obviously in order for the developers to test their newly coded functionality with which they add an additional header entry in the request to some specific sites, specifically, the "main target" is a brand (I've given the link earlier on in this thread). It's obviously an advertisement for the US as that "main target" site is only meaningful to the US public. But it's obviously not the whole story.
If your language is not en-US it's worse than what I've understood.
