Yeah, building Netflix when they first got into streaming was a massive technical undertaking. There were a lot of companies who tried very hard to do streaming video who just never got it to work well enough. Building a Netflix clone is still certainly not trivial by any means, but it's probably an order of magnitude less work than it was ten years ago. When they first shifted into original content production it didn't make sense for HBO to even try to compete with them, but those days are clearly long one.
