That's making an assumption that a brand new Linux user knows they are running the command with superuser privileges.

Half the time you websearch a problem you are having in Linux you will find someone telling you to fix it by running a command that starts with sudo without explaining what any part of the command does. New people probably regularly run those commands without finding out what it does and it probably works (or at least does no harm) a good portion of the time because most people aren't dicks. So then you've got new people trusting that form of advice.

It's hard to blame them, they are new to the system and very few experienced users are going out of their way to explain the basics to new users.

I'm around 20 years Linux user and I'm still installing various soft by curl bashing a script from their site.
