GitHub is many things nowadays. Some people use it sort of like a blog where they can easily post long pages of text, sometimes it's the first thing that shows up in the search results when you search for a computer/phone problem.
I'm gonna sound old here but the younger generations are in general less computer literate than they were back in my day, and a lot of people have no qualms about downloading and running random exe's from discord or mediafire.
Yeah, in my office, nobody had heard of dvorak (my keyboard layout), and they think I'm crazy for using vim. They don't seem to understand how git actually works, and when I describe how compilers work, they think I'm speaking a foreign language. And these are people with years of SW development experience and CS degrees, a couple of them have masters.
I'm older than many of them, but I'm not that old (millenial), yet I'm positive I knew all of this stuff back when I was at their point, as did most of my coworkers. Not sure if it's a "kids these days" thing, or if I was just in a hacker-minded group earlier in my career, but I'm quite disappointed in the depth of technical knowledge SW devs have these days. Oh, and I hired most of them, and they were the better ones of the bunch I was presented with.
To be fair, we're a Python + JavaScript shop, but I still expect devs to be curious about how things work under the hood.
I recently saw an entire org set up with individual repos that were clearly meant to be found in search results for stuff like “comparison tool” (I don’t remember my exact search). It would then lead to a repo that just had a license and readme. The readme would be a full readme that explained the software but linked elsewhere to get it. The link was clearly a malware or phishing attempt.
