So YouTube now reads my google search history and shows me recommendations based on them!

I understand how that's annoying but it is Google reading Google's data, it's not that bad, if it was another service reading your Google search history that's kinda fucked.

EDIT: Didn't mean this to come out as me trying to shit on your parade, I'm a google fanboy and still think youtube shouldn't be using google search history without permission.

You went wrong in thinking it was your data.
It’s there’s.
But yes I agree permission should be requested per service to access that data.

I wish I got youtube recommendations. I keep getting suggested videos and music I already watched.
