I return to my question. This isn't an issue that would bother non-Yeshivish Rabbanim?
Fine fine, they assume it wouldn't bother them. But obviously they approached them in the name of 'unity'. Right? Just like they approached Satmer and Chabad, even though there was a chance they wouldn't join.
They probably didn't. The message at the Asifa will include: Don't watch TV shows online, don't visit sites like Facebook/twitter/pinterest/forums/blogs/CNN/Vosisneias/youtube etc etc.
MO (and also many mainstream orthodox - thus the probable low turnout) has no interest in hearing that.
If you would ask the organizers what they mean by
'You can't live without it', they probably have a very limited definition of 'permitted use'.
I would imagine something like strict business needs, or contacting a company that doesn't have a phone number so you have to email them, booking a flight or paying bills etc (although I would imagine that even bills they would tell you that if it's possible to pay by check - that is preferable)....
Similar to what was posted above, even if porn didn't exist, this asifa would still be called, and the message wouldn't change all that much.
