No, I think that Disney has determined that there are too many corporate interests at stake for a radical political change to occur regarding copyrights, and therefore they want to maintain the status quo and not lose their Mickey Mouse cash cow.

If it were legal to simply copy ideas from anyone without caring about copyrights, I seriously doubt they'd have any issues with doing so.

They've been around just over 100 years and did that once (in the US...I don't know about in the rest of the world).

No, both extremes are bad.

Of course Disney would love endless exclusive rights on all their IP, but if copyright is too weak they can also just copy small creators without negative consequences. Disney wouldn't lose much if a small artist sells a few products on Etsy but could crowdsource all their new ideas for free.
