This is the correct answer. Never forget that US copyright law originally allowed for a 14 year (renewable for 14 more years) term. Now copyright holders are able to:

• reach consumers more quickly and easily using the internet
• market on more fronts (merch didn’t exist in 1710)
• form other business types to better hold/manage IP

So much in the modern world exists to enable copyright holders, but terms are longer than ever. It’s insane.

That’s fair, but OpenAI isn’t fighting to reform copyright law for everyone. OpenAI wants you to be subject to the same restrictions you currently face, and them to be exempt. This isn’t really an “enemy of my enemy” situation.
