That's the point. With "here, copy and paste this code" at least you (can) read what you're pasting into your project.

Most of people learning just "install this module" without actually caring about what's inside or any implementation details.

Licencing is a whole other beast worth of another post.

Oh, I can. So can you. But I assure you, the people you are referring to, those would come right back, requesting letter-by-letter guidance of integrating the code/package into "their" product. Been on SO, seen that, got the t-shirt.
