Aaron Toponce, a systems administrator at XMission, received a letter on Thursday from London-based law firm JA Kemp representing What3Words, requesting that he delete tweets related to the open-source alternative, WhatFreeWords. The letter also demands that he disclose to the law firm the identity of the person or people with whom he had shared a copy of the software, agree that he would not make any further copies of the software and to delete any copies of the software he had in his possession.
