With Google, for example, right now they have a pseudo monopoly in search with 80% world wide market share. With that kind of power, it is very easy to manipulate search results to control what people see which can have a profound affect on society, elections, etc..
Read the class action lawsuit recently filed against Google by James Damore. That at least in part answers this question. Also check out Project Veritas.
> Read the class action lawsuit recently filed against Google.
Depending on your definition of “recently”, I can think of at least three, none of which seem on point (though the UK one about data collection might be arguably connectable to an argument about a need for anti-trust action.)
Well, you sepcified which lawsuit (and it was one of the three recent ones I had in mind), but not how it is in any way germane to a need for anti-trust action.
I actually wouldn't advocate for anti-trust action, I'm just pointing where there is perceived imbalance caused by the dominance these tech companies have.

You literally just did by using the case to answer a question about the need for anti-trust action.
> I'm just pointing where there is perceived imbalance caused by the dominance these tech companies have.
But the case doesn't support that; it supports (taking its allegations—many of which are diametrically opposed to those in the other recent employment discrimination class-action against Google—as true for the sake of argument) a claim of an imbalance within Google, but not the existence of an imbalance in society caused by Google (whether through its dominance in some areas or otherwise.)
