Did it solve the problem? If so, why people had to keep repeating it everywhere the entire time?
Because people are lazy, or new, or for some other reason turned to asking questions of strangers in a public forum rather than making the small effort to look for the solutions on their own.
It's the same reason that Let Me Google That For You was invented.
That's why Usenet is full of posts reading "RTFM."
For some reason, instead of telling people to do that, which solves the problem, we just stopped writing manuals altogether.
