I doubt it. Google/Apple/Facebook/AWS/AWS customers/Microsoft have more non-US customers than US customers, and while the US population might not care, all of those "foreign entities" that Obama explained are targeted without warrants aren't going to put their high-value confidential data into those services now that this is common knowledge.
These companies had better get their asses in gear and get this whole surveillance architecture shut down, or it's curtains for the US internet industry.
If this isn't visibly and loudly fixed, nobody (the 6.5+bn nobodies that don't get 4th amendment protections) will trust US-based companies with high value data ever again. (It may already be too late, if only because if they shut down this one, their track record of dishonesty and evasion suggests they'd just build another and lie about its existence like they did this time 'round.)
There are already European municipalities banning the use of Google Apps on security grounds, for instance. This is just the beginning.

I would be very surprised if the NSA didn't already have the means to crack most, if not all, current practical encryption schemes...
Also, do you encrypt meta-data as well? Isn't that what the whole PRISM thing is?
I would very much like, now more than ever, for services to build on encryption in a way that allows it to be used by everyone, with little to no barrier to entry.
I've wanted to encrypt all my email for a very long time, but the logistics of doing so when you interact with normal people are... rough, at best.
