BS”D:
I know that I’m getting into the game late, but hopefully Hashem will help me in adding something positive to the conversation.
1: I like MW13’s summary of the issue. Filter/Webchaver is a must, and we can go Bidieved (smartphone with gedarim) if needed to be connected 24/6 for work (which is Stam a bad idea, but sometimes needed). And yes, there is room to be Meikel for Hefsed Merubah built into the system (not like you need me to back up Chazal), but you need to have a Rov.
2: The #1 issue is people blaming the internet, finances, shaitels, Tznius, and anything other than themselves for what goes wrong. The famous quote of Rav Yisroel Salanter applies, except that people aren’t big enough to take on Mussar and would rather blame others. Frum Yidden are not willing to be responsible for themselves (and yes, it includes many of the other issues mentioned). Part of being responsible is to have a Rov who knows you well (not running to Rav Chaim K. to see if you need to do Libun on your fork 🙂 and who you can discuss all of these issues with. But yes, finances and internet are huge issues (finances being a very very old one, and internet being a newish one).
3: Girls do not understand the power of the Dark Side. There is such a large potential Nichshol in having anything: A computer/monitor (even without internet!!!), a camera (which can be used to view any type of picture or video, even without internet), or even a telephone (for those in the USA who may remember the old-school concept of 900 numbers). $40 will get an interested bochur a throw-away phone on which they can get anything. This ties into #2, where people have to take responsibility for THEMSELVES (and their children!!) and create appropriate gedarim that work for them. There is no “one size fits all” answer to what is a very large Nisayon of our generation.
