Facebook Marketplace shutdown a home business

I read RNZ news and came across this article. I don't know this couple and I don't know if they did anything wrong, but what really bugs me is that major tech companies can do this without due process or penalties when they negligently get it wrong.

In New Zealand and many places around the world, governments cannot shut a business down without following due process. It seems tech companies make their own rules. How can tech giants do so in a way that affects people's livelihoods in a major way? For Facebook/Meta is it's a drop in the ocean - for this couple, it is their livelihood.
