The Ichud HaKehillos LeTohar HaMachane anti-Internet rally is coming up in a few weeks, on May 20, 2012. What do contemporary halakhic authorities say about the permissibility or prohibition of using the Internet? Obviously it seems like some forbid and some permit. What are the different reasons for and against prohibiting it?
To the best of my understanding, based on discussions with my Rav, no one says the internet is Assur. The Rabbonim feel that unchecked internet has been and continues to lead to moral decay. The gathering is to discuss how to limit its use only for necessary needs, in a way that is permitted.
