It's an equity investment, and yes they're agreeing to a committment to protecting the rights of the creators.

> Disney and OpenAI affirm a shared commitment to responsible use of AI that protects the safety of users and the rights of creators. >Alongside the licensing agreement, Disney will become a major customer of OpenAI, using its APIs to build new products, tools, and experiences, including for Disney+, and deploying ChatGPT for its employees. >As part of the agreement, Disney will make a $1 billion equity investment in OpenAI, and receive warrants to purchase additional equity.

So all those creators that OpenAI plagiarised from, and are suing them, they just needed to pay them to get protection? Sounds easy!
