I was surprised a couple of days ago when Yahoo suggested a couple of new "cards" for my home page. The "cards" had a list of supposed upcoming bills (which was inaccurate) and a breakdown of my credit card spending. Obviously Yahoo has been scraping my email and collecting this data, something I had no idea they do. I immediately went to the Privacy Dashboard and spent an hour turning off all permissions across all of Verizon's platforms (why can't you make it just one-stop rather than nine?).
In any event, I'll not be using Yahoo for anything but mail and I'm phasing even that out. Dumb move, Yahoo.
