For years, Netflix stock has been growing, Netflix has been hiring great software engineers, and people considered them a tech company. But the tech there is not a differentiator. I don't know anyone who will choose Netflix over Disney+ or HBO because of better tech. My brother hates the HBO app, but he uses it because it has content he likes to watch.
Streaming still provides technical challenges, and people will praise providers for great UX, high quality video etc. but in this case, very clearly content is the king. Netflix has had a few years to catch up with competitors who have decades worth of content. It wasn't a lot of time, and they did what they could, but it seems this time is over now. Netflix is no longer the sole player, it's one of a few competitors.
