I am a long time user and advocate of
Linux. I use it daily in my teaching, and have long expounded the many security and privacy benefits that come from using the operating systems.
The problem is, for the average user, it can be daunting thought to make the switch. Despite, this I would encourage you to watch this video by Rob Braxman. In it, he fully explains the underlying structure of Linux, namely the
mainline Kernel and
GNU utilities built on top of it, leading to the many distributions to choose from.
A great watch to better understand
Linux, and whether it might be time to give the operating system a try to improve your privacy.
