The question is why they haven't used stablecoins in this way until now. It's very easy to prepare the infrastructure. Legal procedures shouldn't be difficult to handle either. There is no obstacle to do this, but these companies cannot keep up with the speed of technology. It makes life easier for them to get paid with stablecoins, but it has no effect on Bitcoin. It would be nice if they accepted Bitcoin. By the way, Uber doesn't even exist in my country, the government banned them because of the taxi lobby. It's very strange that there are such differences in the world according to the region you live in.
