The financial cost for whom? If I have to rip equipment out of my walls, that's a serious cost to me. When Google/Nest discontinued Revolv in 2016, for instance, the eventual lawsuit resulted in them refunding everyone's money. So, the reward was 100% loss of revenue, except that it got them acquired. Everyone lost, except the VCs. -- Michael Richardson <mcr+IETF@xxxxxxxxxxxx> . o O ( IPv6 IøT consulting ) Sandelman Software Works Inc, Ottawa and Worldwide
