My kids have never known a time without the DoJ rubber-stamping every monopoly-building merger it could.
The web was new.
It was allowing over the top and disruption of a lot of legacy businesses.
It wasn't clear what constituted a market in those times.
However, by 2009, standards should have been reimposed. That largely didn't happen. Regulators simply got used to letting things go through, and so they kept doing that.
And I'd argue a lot of non-defense government philosophy was also following DoD's "the Cold War is over, budgets will shrink, so defense companies need to merge to survive."

> On December 18, 2023, Figma and Adobe both announced they were mutually agreeing to abandon their merger,[17][18] with Adobe citing that there was "no clear path to receive necessary regulatory approvals from the European Commission and the UK Competition and Markets Authority."

Only if you count UK/EU regulators.
