Last week the internet giant made an announcement that it plans to consolidate more than 60 of its privacy policies into one main document, allowing it to unify customer data across most of its products.
This will allow Google to combine user information from one service with data linked to other services, if that user is logged in with a Google Account.
Although it has been praised by some, such as European Commissioner Vivian Reding, who claimed that Google had been "transparent" and had outlined the changes in an "easily understandable language", others felt that Google should give users the choice to opt out of such a service.
Masiello said that users still have "choice and control", arguing that users have the option to simply not log into many of Google's services, if they do not want data collected about them.
"We're not collecting more data about you. Our new policy simply makes it clear that we use data to refine and improve your experience on Google – whichever products or services you use," wrote Masiello.
"We're making things simpler and we're trying to be upfront about it. Period."
However, many Google users have since commented on Masiello's blog, complaining that Google should give users the option to opt in or out of the policy.
One comment reads: "Nice corporate speak...[but] since it's all about me, why not require me to opt in to your cross-platform program? Would the reason be that few people would and your profits be reduced? Yep. So please don't tell me this change is for me. It is for your bottom line."
Another comment says: "If all you want is to help me, why not give me the option of opting out?"
The changes are set to take effect as of 1 March and users are being notified via email.
