We know things like XKeyscore[0] exist now so I imagine people changed their behavior after that. Having one account for your whole digital life can prove disastrous in terms of privacy. If all it takes is an agent to type in your e-mail and get a laundry list of all your other online activity, then you have failed at opsec (if you are trying to do good opsec that is).
This is why I have several accounts that are insulated from each other and also dedicated accounts for each type of activity (one account for Facebook, another for Twitter, another for Reddit etc). Basically every activity gets its own dedicated e-mail so you can't do cross-correlation of activity and it also limits the blast radius in the event of a breach.
