A few points I wanted to add to the discussion. Hopefully constructive.
1- Sonos, like any other company that makes consumer products, are going to release products before the Christmas retail season, even if all planned features are not yet available. Those that don’t want the product without the promised feature can always hold out until that feature is enabled.
2- Sonos is going to be implementing custom agents, which will open up SVC to any AI agent you want. It’s already been stated that Gemini is on that list of services that will be supported when the feature arrives. To be fair though, it’s unlikely to be same experience as Gemini on a google mini (or whatever speakers they have these days)
3 - I personally don’t care whether Sonos supports Alexa + or not. I do use Alexa + from smart home control where I need to, but I find the push to sell me product, and that they charge for it, I have had Echos for Alexa and Sonos for SVC/music without issue for years, and will continue till I can scrap Alexa. In short, I would understand if Sonos does put effort into getting Alexa + working natively, but I’m also happy to see them not spend any time and effort into it.
4 - I feel as though Sonos current stance on voice actually better matches their originally philosophy with music. Any music service that wants to be available on Sonos can be, and now any AI/Voice Assistant can as well. You aren’t locked into a service, can use multiple services, and switch whenever you want.
