In general it's a good thing that more and more people are aware of the necessity for good security practices for all online interactions - but the belief that individual technological efforts can defeat large-scale corporate and nation-state monitoring is pretty silly. At best you'll just have an added layer of security against things like theft of credit card information by criminal gangs.

If you actually want to do something like communicate with a journalist while hiding your own endpoint from exposure you have to go to fairly ridiculous lengths, such as acquiring a laptop used only for that purpose and which has no associated identifying information, use random open Wifi networks to log onto, and have a decent understanding of the concepts of public-key, asymmetric and symmetric cryptography.

Note that there is simply no way for two known parties on the internet to hide the fact that they are communicating with one another from government-corporate managers of the Internet - although it's possible to keep the content hidded, to some extent, unless your passwords get compromised, which seems fairly easy to accomplish for such actors via keylogger malware installed through backdoor attacks using secret zero-day exploits and so on.

The only real solution is the passage of data privacy laws that provide criminal penalities and which allow class-action lawsuits against corporations and governments that engage in warrantless mass surveillance or the retention and aggregation of customer's personal data in searchable databases.
