Google hi-jacking Pic uploads to Facebook

It seems if you have a cell phone with a camera and upload a picture to FACEBOOK it also hi-jacks the up-load and posts it to your Google account using their Instant Upload feature application on the phone. If I wanted to share that pic with my Circles, I would upload it to Google NOT Facebook. I think it's wrong that Google is doing this and not telling anyone that it is going to happen. Possibly, it's in the TOS or EULA. I don't know, who the hell reads that fine print anyway? Who has the freaking time?
