The last time I can recall anybody trying to make a big deal out of antitrust was in the mid-1990s when Pearl Jam, the most popular rock band of the period, sick of the absurd fees that Ticketmaster adds to concert ticket prices, tried to run a successful national tour without venues dominated by Ticketmaster.
Pearl Jam failed. People seemed to take away the message that, well, sure, Pearl Jam might have seemed cool and their crusade public-spirited. But their economic failure just shows that, deep down, they are losers. What's really cool is having a monopoly.
It's hard to explain to today's youth what a big deal trust-busting was just a third of a century ago. Alternatively, it's hard to figure out why nobody cares much anymore about cartelization.
One difference is that in the inflationary 1970s, it was common for members of the public to suspect that rising prices were caused by monopolistic practices. With the prices of manufactured goods stable or even falling in much of the time since the 1970s, however, it's common to assume that anticompetitive activities can't be a problem because, say, cell phones or TVs keep getting awesomer. Psychologically, it's hard to worry much about whether prices should be falling even faster.
