Do you have read that he/she wrote?
He/she said "some partners" meaning, I think, other companies out of Disney in itself. Maybe are those other factory that have made errors in marketing.
In any case for Disney, consumer products and cinematic revenues are only a small part of the business:
A different thing is for those companies that to produce and/or sell toys and merchandise items, and you could (should) know that Disney is the number one by far in licensing market as Edroger3 said somewhere in this forum. I seem to have understood that he/she works in this area, so I think not talk nonsense. Of course, if you also have experience in this, you can respond with facts and figures to counter his/her claims
