1. I've stopped using Facebook. although my account is still active. 2. Completely stopped using Chrome, it's a privacy-hazard. 3. Installed some of the software mentioned on https://prism-break.org and telling friends to do the same. 4. I've stopped uploading files to Dropbox. For backup, I've purchased an external hard disk of 1GB capacity. 5. I've switched and donated to Autistici mail for personal purposes.

Any more suggestions? You're welcome.
