>Do people work under the assumption that sudo is meant to protect against malicious actors?

I wonder if it comes from having a windows mindset and the way windows screams at you about unauthorized software and forces you to use an administrator password for random arbitrary things while saying it's for your protection. With windows background as a single user operating system, heavily targetted by malware this makes sense.

Then they come onto linux, find out they need to use sudo to install things from package managers or access files in the root directory and immediately that protecting themselves mindset comes into play. However, taking into account Linux's background as a multi-user operating system, this mindset makes less sense as the tools while working similarly at a shallow level, were designed for totally.different purposes.
