That's Meta's response to advertising rules that they find too onerous. Governments keep trying to regulate businesses to appease the voters, sometimes they go too far and the business decides the sensible thing is to leave the market.

This is especially an issue with insurance in disaster prone areas. Insurance company comes along and notices that in the east it's houses very close to the beach (hurricanes/storm surge), in California it's wildfires. Insurance companies raise the premiums in such areas to reflect the risk, the people living there scream. The state does things that mandate spreading the risk--now the dangerous behavior continues but others pay the cost. And those others start screaming because they are paying insurance rates way above the value delivered. And sometimes we insurance companies simply pull up stakes and leave--and we see states responding by saying if you want to do any business in the state you'll provide the homeowner's insurance at a "fair" (not fair, it's a price they're losing money on) rate. I'm not aware of any insurance companies completely leaving a state yet.

We have seen this with malpractice insurance for doctors, though. The biggest carrier simply quit and the market went crazy. Locally we had doctors who would pay more for malpractice insurance for delivering a baby than the insurance payment for delivering said baby.
