Only if you have JavaScript enabled, which people who care about privacy are less likely to do. And even then it's not clear which products it applies to.
Another issue - there's no way to see user votes without actually voting, which encourages people to leave the vote in the "neutral" state and click through if they just want to see the results.
In almost every case I saw, perfect Neutral was skewed very highly so this UX is clearly polluting the results.
