If “Snow Crash” counts, you probably want to look into the novels “Daemon” and especially its sequel “Freedom” by Daniel Suarez. Probably also the novel “Walkaway” by Corey Doctorow.
“The Internet’s Own Boy” is a documentary about Aaron Swartz that I suspect would also scratch your itch. (Available on Archive.org)
If you’re thinking it may be malicious, I think it’s innocuous.
Try cat’ing /etc/skel/.bashrc and see if the code in question in in there. My guess is it will be. When a new user’s home directory is created, it copies all the files from /etc/skel into the newly-created home directory. So, that directory is basically a “new user home directory template.”
The code you posted (is missing an fi at the end, but anyway) just looks like a utility for making it easier to organize your .bashrc into separate files rather than one big file. That’s a common technique for various configuration files that a lot of distros commonly do. And I personally find that technique nice.
If you want to delete that code, it’s not going to hurt anything to remove it (unless someday you add a ~/.bashrc.d/ directory and some file in there “doesn’t work” and it confuses you why.)
Also, what distro are you on?
The sooner the crypto bubble bursts, the fewer victims there will be of fraud like this.
So Wario, then? Maybe that makes Android Waluigi.
