The parent makes a sarcastic comment, based on:

> In the months and years after the 9/11 terrorist attacks, many of us censored what we spoke about on social media or what we searched on the internet.

from the TFA.

i.e. Which those "many of us" were, and what "social media" were they censoring themselves in around 9/11?

Since

(a) the only successful website that one would classify as "social media" back then was MySpace, and

(b) it was mostly for teens,

(the parent asks) if people on social media back then censored themselves, does that mean that teens of MySpace censored themselves? Either the article is BS on that part, or teens at the time quite politically aware....
