Frankly speaking, because no-one is forcing them to stop serving them.
That's the biggest 'trick' companies like Google have pulled here. They've somehow tricked the regulators into thinking that because they're big companies serving a lot of customers over the internet, that any sort of fraud or product liability laws are irrelevant to them.
Because any other company doing this would get sued into oblivion, shut down and the executives criminally charged. If a brick and mortar business let blatant scammers and criminals advertise in their physical stores, that would be seen as a serious crime.
Same with a retailer that sold dangerous or counterfeit products, or one that turned their stores into surveillance panopticons where customer data was collected illegally and sold to the highest bidder.
Google, Amazon, Meta etc are doing things that would get a normal business owner sent to prison.
The solution isn't just technical, it's about being willing to enforce the law for internet businesses the same way we do for offline ones. If Sundar Pichai and the board were looking at 10-20 years in prison for fraud or cyber offences, then Google would fix those dodgy ads real quick...

Is it false ?
As much as we can lament the current state of affair, we must acknowledge everything that has been thrown at any of the bigger companies has resulted in slap on the wrists at most.
At this exact moment in the US money is straight power, in it's rawest form.
Well no and that's the problem. Many governments (especially the United States one) are complicit in this. They don't do nearly enough to keep corporate power in check.
If they really wanted to fix these issues, antitrust could be a real thing again, and companies like Google would be forcefully broken up and barred from remerging later down the line. If Google doesn't have Gmail, Chrome, Android or YouTube and all these things are separate businesses, then their power is severely curtailed.
They could also arrest CEOs, board members and other people with a large amount of power at these organisations and charge them for the actions of the business.
Or levvy percentage based fines that obliterate the company's ability to function. Could Google function if it was charged 50-60% of a year's worldwide revenue until an issue was fixed? It'd probably have to cut way back on everything in that scenario.
The issue is that the government has been so thoroughly captured by corporate interests that noone faces meaningful consequences if they earn more than a billion dollars a year.
