I recently read a Business Insider Article article which explains how to opt-out of displaying my ratings and feedback I had provided to apps and services found across the Google ecosystem- I assume this mostly means search results and profile pages in the App store, Maps, etc. What I found quite telling and annoying is that I'll assume this only works one-way; only positive endorsements will be displayed.
My reaction to this is simple- why would I care? I can only imagine google would share with me positive feedback, not negative feedback. For me to make an informed decision I would need to have both- to understand the pro's and the con's. I'll assume that Google makes money on the pro's and has a real risk of losing money (through litigation) by displaying the con's.
