A few more thoughts:
1) Part of the reason this whole thing is coming up is that Apple said that were going to modify the encryption on iPhones so that they couldn't decrypt them either. It's at that point that the big push for breakable encryption started. So, saying that this is just about companies giving the NSA data that the companies already have isn't true. A subpoena/NSL/FISA court order is sufficient for legal access to data that the companies already have. If that were all the NSA/FBI/etc wanted, then they already have the tools to get that data.
2) given that, it is imperative upon the people asking for the change to explain why supoenas/NSLs/FISA court orders are insufficient. I haven't heard a single thing about that, *except* in the context of companies like Apple enabling encryption and *not* escrowing the keys. That puts a lie to the idea that this is just about accessing data that the companies already have.
Lastly, please don't make "talk like adults" sideswipes...you're assuming bad faith on the part of your commenters, (me, in this case) which you have no evidence of. This is a very passive-aggressive way of insulting your debate partner. If you'd really like to debate, this is not helpful.
