Verdict
Yet, the ethical line is razor-thin. Using Selfishnet to ensure a stable connection for an urgent work deadline, while a neighbor torrents files, might seem justified to the user. However, the tool’s design inherently lacks consent. It overrides the fair, default behavior of the network without the knowledge of other users. Legally, using Selfishnet on a network you do not own constitutes a violation of computer fraud and abuse laws in many jurisdictions, as it involves intercepting and manipulating network packets. Furthermore, the tool’s "selfish" namesake encourages a zero-sum mentality: my speed comes directly from your inability to connect.
SelfishNet is an exceptionally powerful tool, and with that power comes significant responsibility. Using it without considering the ethical and legal implications can land you in trouble.
