content: I would avoid every google and facebook products they are spyware and share/sell your data and I think Twitter is also bad. All these encrypted companies collect, store and share your data. I'm not sure if the data ain't decrypted and read somewhere in the middle of the encryption proccess but I wouldn't trust too much in the big tech companies protection of your privacy. Your safety depends much of decentralization, anonymity and encryption and almost all these companies have lots of points of failure and are susceptile to middle man attacks. The biggest threat to your online safety is probably your behaviour online because humans are lazy and undisciplined and will not keep their sensitive data compartmented and will use the same phone numbers, passwords, emails, usernames, buddy lists... in many different places online and that will make it easy to track you and identify you when you attract the wrong people attention.
