The revitalization is happening as we speak. Normally Big Tech would have been able to rely on establishment Democrats and Republicans to avoid antitrust scrutiny. But Democrats are on board with the progressive wing now [1], mainly as a result of seeing the fallout of Google/Facebook/Twitter's role in enabling Russian influence operations in the US (and Europe), but also because newspapers and rivals of Google have been campaigning for it for years (Foundem in the UK and Yelp in the US have been massive thorns in Google's side, as well as the entire FairSearch group). They were successful in the EU (the shopping and Android cases are slam dunks in my opinion) but were stymied in the US under the Obama administration (despite FTC staff recommending a case be made) [2].

The exciting, and refreshing, thing about the revitalization is that's its bipartisan in nature. The Bannon wing of the Republican party are targeting Google/Facebook for the perceived threat to conservative speech and likely because the companies are too liberal, the Warren wing of the Democrats are concerned with concentration in markets. The mainstream of the parties are more open to these arguments than ever before. A Republican attorney general opened an antitrust investigation against Google [3]. That's dangerous water to be in if you're Google or Facebook.
