I'm not a fan of Google's, but I'm not sure why people are unwilling to recognize this is a significant step in the right direction.
Before Google took the steps necessary to ensure communications between data centers was secured, the government could (and apparently did) just slurp up everything and troll for information. Now, at least they'll need some sort of court order, which means they'll need at least a modicum of an idea what they are targeting.
The entire government system is still deeply - maybe even fatally - flawed. Even if Obama's reforms actually take place, there's still far too much power left in the hands of the secret courts and the spy agencies. But fixing this horrible, unconstitutional mess will take time and effort. Correcting (or, in this case, interfering with) even one aspect of it is welcome news.
