The main argument artists use isn’t that it is taking their job. The problem is that it was trained on their work without their consent and without compensation. This is fundamentally different from a Wordpress or squarespace and arguably different from models trained on open source software only.

Ask them how they feel about artists licensing their work for being training material.

Plenty of them are going to respond just as negatively to that.
