Something about "Hey Siri, ..." is much more grating to me to say than "Alexa, ...". Maybe it's just that conjunction of phonemes being rare in English?
But in this case it doesn't work. I don't repeat the name "Chrome" 20 times a day like I will for a Google Home. This is a serious f*cking flaw and it actually makes me worry for Google's stock price that they can't see how obvious of a problem this is and/or are too paralyzed to fix it.
Try saying that three times fast. Actually, try saying it just once fast.
I always end up spitting out something like "Okaygggeellggglle"
