What is it with Android, that it constantly wants me to use Live Wallpapers?

I switched to a plain android device from Xiaomi and I really like the calm experience. No ads, no duplicate services etc. But one thing still bothers me: Live Wallpapers.

Why is Android so keen on activating live wallpapers? I didn’t want them on my old device and always thought it was a Xiaomi thing. But now I still get a screen every once in a while and after each system update. Why? What’s in it for Android that it is so obsessed with fucking live wallpapers that I constantly have to reaffirm that I really REALLY don’t want them?
