I disagree. There's no way marketing could have made HomePod a success. HomePod was an ill-conceived product. It was too expensive and too limited compared to other smart speakers. No amount of marketing was going to fix that.Agonizingly. One of the rare cases where Apple's marketing snatched defeat from the jaws of victory.
The emphasis on audio quality was pointless too. The smart speaker market doesn't care about audio quality. The market that does care about audio quality, the market Sonos rules, would never have been interested in the HomePod because it lacked so many necessary features. I don't blame marketing. I blame the the team that created such a half-baked product and thought anyone would actually want it. Beyond hardcore Apple fans who continue to sing its praises on forums, absolutely nobody was interested in HomePod.
