Any popular OS would have the same issues. Linux on the desktop is not established enough to have many casual or low skill users in business environments. Given that, there aren't many software vendors pushing the edge of Linux and therefore not introducing new vulnerabilities that have a large install base. Attackers won't go after low yield platforms when they can get better fruit from the popular ones. There's not much need to socially engineer normie users if they aren't on popular OS platforms and app ecosystems. History has already proven this true. Linux is not any safer than Windows or MacOS. It would have just as many holes in it as Windows if it were the leading OS with all levels of users. There is no truly safe and secure operating system and we shouldn't pretend that FOSS is immune to failures and attacks. It's just not popular enough to see such grand failures. That will change over time, but Linux already has had some high profile failures of its own so we have had a taste of what it would be like if Linux became as popular as Windows on the desktop.
