I already pay them $5 a month so I can use myname@mydomain.com for e-mail (I believe this also exempts my inbox from their ad-based data mining, but I could be wrong) I would gladly up that to $10 or $15 a month to extend that across all of Google's products (Youtube, Search, Maps etc.) and have advertising stripped from the whole thing and my "peronalization" data sandboxed so it doesn't get leaked to the "free" version.
The difference that I see between FB and Google is that I would trust Google to get that right. I would expect FB to say they sandboxed or protected my data and then have it turn out in court in ten years that they did no such thing...
