Part of what big tech has done is to divide us from one another and "curate" our information spaces to make it feel like we're the only ones experiencing these feelings, like we are the only ones who are actually as desperate for change as we are, when the reality is that I think everyone is actually on pretty close to the same page for a lot of the same reasons. Believe it or not, we do all inhabit the same reality, we have just been made to feel that that reality is itself fictional. It does not serve big tech or big media or big government's interests for us to know exactly how much we have in common, because they don't want us to find a common purpose.

Tl;dr: the author if the article isn't a leftist and really wants everyone to know that.
