Steve built a culture where user experience was the core business driver. Yes, things like Antennagate still slipped through the cracks, but ultimately user experience was still the core. He believed that if you get the core user experience right, people will buy your products.
Since Steve's death, Apple have been riding on that legacy while putting profit as their core business driver. People still buy Apple products based on that legacy. They expect a joyful user experience. Instead they get a buggy, over complicated mess (assuming they successfully navigate their ridiculous product line up). They get eye strain. Their devices bend or slip out of their hands. They get hours and hours of frustration. They loose data. They get features that don't work in their region. They loose money. They come to MacRumours and post their experiences. They get told to try different apps. They get told to go to Android.
People want the user experience Apple used to provide. Going to Android or 3rd Party apps won't help someone get that experience. People download updates hoping that experience will come back. People buy new products like the iPad Pro or the MacBook, but the experience just isn't there.
Some users think that experience can still be found in Apple products, and sadly, I think many of these people are in denial. There are definitely still some elements that have that "Apple" factor, but mostly it's history.
