There are a lot of reasons one might wish to maintain privacy in our increasingly digital world. These can include being a private person, wanting to escape an abusive ex or parent, seeking reproductive healthcare in a hostile environment, being GSRM in a hostile environment, wanting to disrupt the surevilance capitalism model, engaging in activism against large corporations or government actors, building a mutual aid or support group for these topics, trying to protect those who do these things, and other use cases as well.
These resources are a starting point for your research. Depending on your threat model (who you intend to hide your communication and activity from), you may need to utilize many of these resources. You should seek to have defense in depth, relying on multiple layers of security rather than a single type of protection. And be sure to look for resources beyond the ones mentioned here.
