They don't make it easy to discover content. They still have quite a lot of good original content that isn't promoted and a slew of third party things that aren't promoted or discoverable at all unless they happen to make the trending list
The majority of their original, promoted content is watered down crap designed for mass appeal.
For TV shows, when they do produce something of quality they often dump it if it doesn't find an audience immediately or it doesn't drive "new subscribers". Leaving a bunch of stories half told doesn't give me the confidence that it's worth the investment to start on their new content. This is especially problematic because it is a vicious cycle where since they aggressively cancel stuff that isn't performing, people don't invest their time in new stuff because of the expectation it gets canceled, means more new stuff underperforms, leading to more cancelations, and further eroding the trust of viewers. It's also negatively impacted by poor discoverability.
Their UI is seemingly optimized to shove their latest broad appeal stuff in my face and seems to deliberately make it hard to find anything else.
