Activists, minoritized people, working people, students, disabled people- many of us have limited resources. A good rule of thumb for security is to only put as much effort into your security as is necessary. If you’re planning civil disobedience, or if you are part of a targeted group like trans people, undocumented people or Muslim people, put more effort into learning encryption software and encouraging community adoption. If you’re making plans to get ice cream, using plain texting might be fine for that situation.
