We all knew it for years, that's right, but they let a 3rd company give the data to a 4th company. and that's what I and the rest of the world are trying to figure out. how did Facebook let this happen?

The one thing I know for a fact that is Facebook will stay here forever and will forever be the biggest social media. no matter what will happen.

It's sad because I got F a lot by them, but what can we do...

They lost 17% of their value but I don't think they are even worried, there is no reason for them to be.
They have Whatsapp + Instagram as well. but it doesn't really matter anyway because Facebook will stay as big as it is.

It's the human nature to forget, this whole story will be forgotten within a month or so.
