The point they're making -- trying to make but maybe badly expressed? -- is that IF these lawsuits against AI developers like Stable Diffusion, MidJourney, et. al is successful and the technology is ruled derivative/copyright violating unless licensed by Big Content then ONLY  Big Content will be able to use it fully. Sites like Wombo & MJ will be so restricted, censored and crippled as to be useless except as cash cows for those who hold all the model licenses.  The jobs and rights people think they're protecting with these anti-AI lawsuits and protests will end up being lost, not because of Jane & John Doe making waifu renders in the style of Some Famous Artist and posting them on Art Station or selling prints on Etsy/Wherever, but because studios run by House Of Mouse, etc. will be using their own perfected AI systems for darn near everything because (A) faster and (B) cheaper. Big profits to be had and to heck with fair use/fair dealing and the public domain.

That's my take on it, no doubt there are other articles out there -- written by actual human beings who know what they're talking about -- that can explain it much better.
