When you buy content from a legitimate provider, part of what you pay for is reliable, consistent, quality service. You don’t get that when you buy from pirates.
Because they offer content that they have no right to, pirates are always under threat of being shut down by government authorities and the content’s rightful owners. And when pirates get shut down, they disappear, with no recourse for their customers who may have dropped hundreds of dollars for an illicit streaming device, or pre-paid for service.
Doing business with people who sell what isn’t theirs is a gamble. And there’s a good chance you’ll find yourself on the losing end.
