While I lament another monopolistic tech giant yet again dodging the most meaningful regulatory consequences of their actions, the more useful meta-question is how these behomoths are now so reliably skirting major enforcement like break-ups. It's not that judges have gone soft or just that the current admin is nerfing enforcement (though they are), this trend goes back much further.

The biggest factor is that tech giants now 'pre-game' major anti-trust relevant actions through an internal compliance team staffed by former regulators. The result is the slam dunk smoking guns of 20 years ago are rare. Today's monopolists artfully push right up to the line between "red-handed" and "arguable". Then take measures to fuzz that line and kick up clouds of plausible deniability in the record. Imagine how hard it would be to convict an embezzler who was carefully coached during the crime by expert former prosecutors and forensic accountants.
