It's funny that you focus so much on the Custer's Revenge part, since that literally took the least effort.

I agree that using the meme wasn't too much of an effort. But I consider the creative process I had to be:

1. Make an observation that the AI Image ideas are lazy.
2. Think of an appropriate meme format that fits my opinion on the matter.
3. Create the meme without a watermark (that's more technical than creative)
4. Think of an atrocity that's not too much in bad taste (I don't want to make fun of the Armenian genocide). That's literally the last few seconds before I posted.

That's it. Making the observation and finding an established term to express that in the context of a specific community is IMHO way more creative than being the n-th person to think "wouldn't it be fucked up if Disney made this?"
