I disagree. As a user, I don't want my queries passed on to the sites I visit for privacy reason. As an advertiser, I use the organic keyword reports to buy ads frequently.
It is very common that I would find organic searches where we got conversions, but were low on the page or on the second page. I would use that information to buy ads. For the last year or so, this technique hardly works because there is so much less keyword data available. Now it is completely gone as you can't match the webmaster tools data to conversions.
This change is going to cost Google significant revenue and growth over time.
What privacy reasons? As soon as you land on that site, they can geoIP you, evercookie you, browser thumbprint you, and if they participate in network-based cookie lookup systems, they can probably even identify who you are. Why does the keyword you searched matter at that point?
