A lot of the frustration from Sonos users is fair as the company has promoted that their products are constantly supported - so you have confidence that your product will continue to work AND be updated to get even better. Not only did the marketers behind Sonos say this, but their end-users and retailers also picked up this story, so they pushed other people (customers / friends and family etc) the line. Now they have the potential to have egg on their faces, so they're pissed.
Remember when Sonos launched a big campaign to decry the weakness of Bluetooth? Now they have a product with Bluetooth on-board.
They have an image problem, whoever is advising them isn't getting it right.
This industry is not getting cheaper and cheaper, we're simply convincing ourselves that we have to push the cheapest option to customers. #makesonosgreatagain
