Most of the internet and servers are run on Linux for stability, low overhead, versatility, and package support. I'm aware that there is no OS with perfect security or anything, and that the more secure you get the less usable it gets, and logically that would be true..except for MacOS.. MacOS right now is the leader for desktop OS security (security =/= privacy) second only to Qubes and it's extremely usable. I mean people don't pay $2500 for them to not be able to use them.
