I&#x27;ll guess, totally uninformedly, that most PC users&#x27; data&#x2F;privacy gets breached because of their use of insecure third party services and&#x2F;or their insecure use of third party services.  That is, their credentials get stolen, the databases of the services they use are leaked and the service is late to realise the attack, they do not sanitise input and pass it directly to the database, etc...  If my guess is correct, then using OpenBSD or GNU&#x2F;Linux or MSDOS won&#x27;t help, the users need to be informed and educated on how to securely use the online services.  We already have the infrastructure: public schools.  A couple hours on a week for a semester can be spared for a personal computing security lesson.<p>I really doubt the actual effect of using OpenBSD or whatnot on a PC users&#x27; security.  It is a clean and beautiful OS, and if I wasn&#x27;t blocked by hardware (ath5k, Atheros ARBXB63 on Asus X51RL, help appreciated) I&#x27;d use it (I use FreeBSD and I love love love it), but I don&#x27;t think, as a PC user, it is necessarily considerably more safe in practice than a well-built Linux distro.  _Server is another story though_.
