what the FUCK

While I don’t recommend tracing as a primary way to learn how to draw (use IRL studies), as long as you respect your sources, tracing can at least help you with pen strokes and line art. 

Again, respect your sources. If you don’t have sufficient licensing to use someone’s work a certain way, don’t cross the line anyway. Try something else.

I would write an obnoxious essay on some useful/better drawing techniques if I had the energy, but I’m mostly pissed the FUCK off at the vitriol and the black-and-white thinking going on right now.
