They can pull the code out of a magical oracle somewhere in the misty mountains for all I care, as long as they can telle what the code does and why it was placed there. If they can't, it's rejected. Use whatever tool you like, but the buck stops with you.
My problem is a co worker has put an OK-ish wooden toy train in front of me presenting it as their own work, so I take some time to show them how to hold the plane for a better finish on the grain, how to pick timber so that the knots are faced inward, and how contrasting stock takes up wood stain in different way highlighting the elements of the piece.
They nod politely, go back to Ali Express and pick a slightly different toy train to present as their own, commit it, and move on.
At some point that employee has to be shown the door, because you can also order from Ali Express yourself, you don't need a well paid employee to do that that doesn't provide additional value.
