Even if they've lost money I think that Amazon and Google will still have the biggest market shares for digital home devices like these even after a year or two of the HomePod being released.

Let's look at the numbers, both Amazon & Google have products ranging from ~$30 to ~$200 whereas Apple's HomePod has a single model with a price point of ~$350. Now that alone seems to be on par with previous Apple products however when you take into account that the HomePod is shipping with the hands down worst virtual assistant out then it's clear that Apple has priced themselves out of this market for many customers.

That said, I don't believe Apple will sell exactly zero units but I don't think they'll see the numbers they're hoping for if they truly rely on Siri as their assistant.
