The parent is referring to the blocking of an acquisition. There have been many examples of that type of action on the basis of competition concerns. The Justice Dept and FTC routinely try to block acquisitions where there are competition concerns. They don't always win, as in the case of AT&T / Time Warner (or in the case of AT&T / T-Mobile, they did successfully prevent that). Some other examples: Anthem & Cigna, Sabre & Farelogix, Edgewell & Harry's, Office Depot & Staples, Sysco & US Foods.

A little over a decade ago, a lot of stuff went wrong because a bunch of economically dominant corporations figured they were too big for governments to allow them to fail.

And it looks like big tech is developing much the same rich-and-out-of-touch reputation that bankers and stock traders used to have.

I don’t know who, but I am assuming one of the FAANGs will be forcibly broken up in the next decade.

How'd that work out for the bankers and stock traders?

It worked out pretty great for them, everyone else though... not so much. The bankers got to enjoy inflated profits and bonuses for years knowing that the government would step in when things eventually blew up.

Privatizing the gains and socializing the losses is a playbook the tech giants are all too happy to keep pushing as long as the government allows them to.
