Privacy sure Linux has it beat. Security? Simply untrue, particularly by default, unless you put a lot of time into configuration, in not exactly sure where that narrative is from it’s completely false. macOS for example has way better app permission isolation that Linux does unless you use only flatpaks. Also the open source system scanner that gives devices a cybersecurity score that I’m forgetting the name of at the moment can be used to prove this correct without going into extremely long detail. Compare the results from macOS and Linux by default and it’s pretty solidly in macOS favor. I use both but this idea needs to stop being spread simply because people have a vendetta against closed source. I love Linux probably more than macOS but there are still reasons to like and use macOS.
