This is a threat to the existing donor class in Washington, which has embarked on a project since 1968 to build power through political donations, the courts, and crushing labor.
Granted, America has done such a piss-poor job of actually enforcing antitrust laws already on the books that it's hard not to read into this enforcement now as the end result of someone refusing to play ball.
Or will it go after services people love, that are free, or that revolutionize industries?
Your assumption about the implications of bipartisan support seems a little Pollyanna-ish about the degree to which politicians represent their constituents on any given issue.

[1] I guess this isn't that weird, given that similar inconsistencies shows up in all sorts of polling.
Depends on which companies you're talking about. There's widespread discontent about social media companies, but the left and right wing of the political spectrum have opposite and incompatible discontents, so I don't think it's justifiable to call it "bipartisan grassroots discontent". The non-social-media "Big Tech" companies remain extremely popular and well-regarded in surveys of the general public. Google, Amazon, and Netflix were 3 of the top 5 most loved brands of 2020, losing out only to mail carriers (and Google took second place, ahead of UPS). Google and Amazon each have two of the top 10 spots (Google + YouTube, Amazon + Amazon Prime). The idea that there is roiling popular discontent about the activities of Google and Amazon is entirely a media fabrication.
