Cherrybim,
Why do you say that it would be hypocritical? Is it assur to see/hear Torah via the Internet? Certainly not!
I assume you’re addressing me.
Note that I said “somewhat” hypocritical. You are correct, that it’s not inherently assur to access the web for purposes of Torah. The issue here seems primarily to be that the yetzer horah to access inappropriate material is so strong, that the poskim feel that unfiltered web access is completely assur, and even filtered is only acceptable if necessary.
There is a quandary as to whether or not Torah based sites are worthwhile. The upside is quite obvious. The downside is much more subtle, but quite compelling as well.
Since even filtered web access is not recommended (for obvious reasons – filters are far from perfect or impenetrable), there’s a disadvantage to these types of sites’ availability, since their existence encourages, to some degree, web access.
By not (intentionally) making it easier for someone with web access to obtain a recording of the event, the organizers are being mechazek those who have made the commendable decision to keep away from all web access.
