This helps explain why Sonos might have taken this action: "Sonos has claimed that it shared details of its technology with Google starting in 2013 when the two companies began working together. Initially, Google was not a competitor, but it started moving into Sonos’s space, first with a small device to stream music in 2015 and then with its Google Home speaker in 2016. Sonos said Google was violating more than 100 of its patents and proposed a licensing deal to Google. The two companies were unable to reach an agreement."
