That's not a charitable reading of the comment, and furthermore, it's not even a reasonable assumption. Other comments clarify that the "theft" is in quotes because it's a figurative theft, not from Disney to themselves, but from Disney to the earlier, non-copyrighted folk tales it drew inspiration from. And the "theft" is that the Disney IP supplanted (via ubiquity) the public domain versions to the point lots of people aren't even aware they exist. Nobody is arguing it's literal theft, hence the quotes.
