I 💙THIS! Signal went ahead and used Facebooks targeting system to send very plain descriptions of how you are being tracked.
We created a multi-variant targeted ad designed to show you the personal data that Facebook collects about you and sells access to. The ad would simply display some of the information collected about the viewer which the advertising platform uses. Facebook was not into that idea.
Facebook banned them.
