Perhaps controversial but I think the ability to ship continuously is also a factor. You just have to pass and fix the things with the most complaints after. A holistic view on the general user experience will never make it to the top of a pile now.

I think yearly releases were much better. I feel a lot of sites and software now have constant change you can’t keep up with and often the change doesn’t really improve anything. Reddit would be a good example. I constantly have buttons disappear and rep appear or move around. Same in YouTube. Much friction for no benefit.
