It turns out that Facebook could in fact use data collected from its Portal in-home video device to target you with ads - Recode

I absolutely love that Facebook themselves had to correct publications on this clarification.

But Facebook has since reached out to change its answer: Portal doesn’t have ads, but data about who you call and data about which apps you use on Portal can be used to target you with ads on other Facebook-owned properties.

So when you give your photos to Google and Facebook they mine brands and objects from them to advertise to you. WIth this Portal surveillance device they can watch the activity in your house to then shove things in between cat pictures on Instagram. Don't buy one of these. And also, ditch Facebook Messenger too.
