Given there seem to be a significant number of SMBv1 devices out in the wild, Sonos could easily have left v1 in place while adding v2/3 for those of a nervous disposition.
Not everyone wants a new usb router or another expensive clunky black box or to run a windows machine 24/7.
In fact, they could just as easily reinstate SMBv1 (but on current performance, pigs might fly first).
Only Sonos really know the answer to that and they aren’t keen on sharing anything 
Forums and social media generally provide a snapshot of people having trouble, rather than the number of active customers. I only …
Would that include the silent majority? Many of whom, on discovering their speaker no longer works as before, just consign it to the landfill. Or stick it in the cupboard. I've got a couple of old laptops been gathering dust for years after they ground to a halt after one more update.!
Any majority change, whether vocal or silent, would be visible or potentially identifiable depending what data is shared, but it doesn’t mean it’s a bad thing when shifts occur. There is always a fine line between sharing interesting/fun data and exposing too much which can stray into real company confidential. It takes a different mindset and culture from the top down and would certainly be a bold step, potentially industry leading, in an industry that doesn’t traditionally operate that way. It’s not a seismic shift from the current quarterly financial or board reports many companies already publish though. 
It’s the same sort of shift many tech companies went through where every mistake or outage was a secret, to it now being far more normal to accept things go wrong and explain why. Companies are full of people and everyone makes mistakes, everyone can relate to that.
I expect myself to be in a niche group of a small group of users, as I buy digital downloads to own and use both a local library built from physical and digital download & own media as well as streaming. I have no idea though. Some people I work with have never bought and don’t own a physical or digital version of any media.
Over time my usage pattern has changed, I rarely buy a cd anymore, favouring a drm free digital download when I buy something I like enough to want to keep. I stream internet radio and from an online service daily for listening and discovery.
