It sounds like your country is the weird one. Try burning the complete works of Disney onto stacks of DVDs, then go down to your high street and hand them out. See how long you get away with that for.

I think the big difference is distribution vs consumption. Where I live, there are additional clauses in law, for mass reproduction and selling.

But republishing any work as your own, probably falls into that category. And it isn't about profit, but commercial use; thus pasting onto a blog to improve your business (rankings, hit count) is a business use case.

It's ultimately a commercial use because you are directly affecting Disney's market. This should be obvious.

Unless I do like millions of them, literally nothing would happen.

Do you think they would act much faster if you charged a dollar or five? I don't.
