For Sonos, that usually means they want to sell a few more devices before they drop support for them and make them unusable for everyone with a final update.
Unlike say Apple rolling out a Gen 2 which won't stereo sync to a Gen 1 discontinued just a year or two ago???
Move Gen 2 is an improved Gen 1. I have Gen 1 and it sounds fantastic. Unlike Apple, Gen 1 still pairs with any of the newer speakers.
I don't recall EVER reading something about a Sonos speaker being made unusable by software support. Perhaps you can point me to any one example of that from a reputable source?
There is a split of relatively old Sonos speakers grouped for the S1 app, but those still fully function with that S1 app. For the last few years, their line is grouped for the S2 app and work well. If anyone had both, they would simply use 2 apps to manage respective speakers... which seems much better than say proclaiming a long, LONG life product like a speaker "vintage" because someone doesn't want to keep supporting the iOS-based tech "smarts."
In one scenario, consumer has options to keep using pretty old speakers. In the other, it's basically audio iMac screen, "throw baby out with the bathwater." Thus, THIS Apple-everything guy has Sonos speakers where I want "smart" speakers. They work just as well as HPs- including with Apple Music and Airplay- but are not walled garden locked down so they work with
ALL music services too. When I want Siri or HP-like smarts, I use the Mac or iDevice or AppleTV which has those same smarts built in too. HomeKit is just as functional so "play AM playlist in whole house" works the same, as does "Play <whatever> in Living Room."
The "dumb" part of speakers we actually hear should be good for 10-30 or more years in a good speaker. "Smarts" put that in jeopardy unless the seller wants to keep maintaining those smarts to keep them playable. Sonos has illustrated a willingness to keep very old speakers playing. We can only hope that Apple is as willing to keep the iOS-based "smarts" for this ONE kind of product functional for 10-30+ years. Else, we'll be throwing out the dumb parts too- like perfectly good iMac screens- when the smarts are made obsolete... over and over again.
