The "you shouldn't need privacy if you aren't doing anything wrong" is such a tired yarn.

There are many many many examples of abuse, both in the short term (flock gymnastics pedophiles, cop loveint, cross state abortion suspicion tracking) and long term (the "red scare", the administration performing loyalty tests). There are also plenty of discussions outlining how everyone should support privacy because some need it more than others and we're all on the same team.

Pretending people who are against flock or government illegal surveillance care more about criminals then their families is so bad faith it makes them an asshole (not you but a comment above).
