ELI5: why do some companies limit online services in certain countries?

For example, Netflix. Wouldn't they have more customers if they provided all services all over the world?

If a company is restricting services, it is generally either because they cannot carry out those services in that area (no supply network, for example), it is simply too expensive to carry out their services in that area (taxes and tariffs there might be higher and eat into the margin until it is not profitable) or it is not legal.

With Netflix in particular, the right to stream a certain program is bought per region / country. So if Netflix USA buys the right to air Supernatural, that doesn't mean Netflix in France has those same rights. Often what happens is that rights to air in particular regions have already been contracted out to other services, or that they are asking a higher price than Netflix is willing to pay for those rights, so Netflix doesn't / cannot acquire them.
