This has nothing to do with the OP &#x2F; what library books were read. The <i>library</i> certainly does know what you read. Likewise, Google and even real people at Google may know what you watched. But that&#x27;s not surprising. It&#x27;s to be expected.<p>The real comparison is if Google gave that information, de-anonymized, to advertisers. Then there would be an issue.
