Plenty of people genuinely dislike the disregard for labor and intellectual property rights that anything Gen AI represents. Again, an authentic moral position.

"Virtue signaling" is for example, when a corporate entity doesn't authentically support diversity through any kind of consequential action but does make sure to sponsor the local pride event (in exchange for their logo being everywhere) and swaps their social media logos to rainbow versions.
