I didn’t even address the laughable suggestion that the yeshivos are…ok…with the Internet. Do you remember citfiield? Do you remember rav vosners psak that one who has unfiltered internet is pasul le’adus? The yeshivos have not wavered on their opposition to the Internet. The same rules that were laid out then apply now:
Best not to use it at all
2nd best is only at work
If not, only for work at home with a very good filter, not in a private room, and not letting kids near it under any circumstances
If necessary, shopping is allowed as a big bedieved
Recreational use was never permitted on a general basis; individuals may have heterim from their rov for extenuating circumstances.
Torah, etc – if one already has internet for a legitimate purpose, many are ok with using it for learning and shiurim. Many aren’t. That’s a big split nowadays.
I don’t know who told you that yeshivos are ok with Internet use. It’s as big of a lie as the MO people who say that the satmar rebbe wasn’t against the state of Israel (sic)
