No, it shouldn't. Maybe you should be, at the very least, considered a questionable person. I do not in any way or form consider anything to be wrong with what they're doing, but I question the senses of someone thinking this is immoral or even evil.
So were it to be the case that we should consider building an AI by scraping people's publicly-available work without their consent to be immoral (as many whose art was scraped to build e.g. stable diffusion would argue it should be)...
Do you not agree (in that context) we should consider scraping the output of an AI generated via such an immoral process to create yet another AI also immoral? At the very least, I'd think we would consider it further laundering of other people's labor with just extra steps.
Keep your subjective nonsense out of this.
