You left the last sentence out of the paragraph from their ad copy. It doesn’t make their practices OK, but it’s important for those who don’t click through:

> We should note, however, that this data becomes aggregated, removing personally identifiable information before it is received by advertisers.

It's not that important though, because depersonalized and even aggregated data can be traced back to a individual and even if roku doesn't hand that information along with your account details to advertisers roku themselves still have it all linked and can sell/leak that info to anyone at any time.
