          I mean security through obscurity is a real thing. It’s not real security, but the risk of attack is still lower than it would be otherwise. It’s the primary reason Macs had so little malware at the time and Apple’s marketing leveraged that for billions in advertising. Generally malware creators target the maximum number of devices, and MacOS and ChromeOS are small pickles compared to Windows.

Most malware is based around striking as many victims as possible quickly before it is discovered and the exploits patched. doesn’t matter.
