I think my #1 reason to stay Apple for the foreseeable years is that they put Privacy up there as a value. It makes all it's money from hardware and not my data. Once you understand how Google makes it's money it doesn't make you want to use it's products.
Homekit may not be as good as Alexa/Google assistant for home automation but it makes an effort to keep all your data local and not in a cloud. A small minority of us really value that.
I understand for regular people though it's really just a status symbol. I spent X on a phone cause I'm doing well in life.
