To handle noncompliers, they can get off of the various App stores with a simple DMCA request, no complicated lawsuits required, unless the developers appeal the take down, which probably involves a lot of "under penalty of perjury" lying.

Why would breach-of-contract have anything to do with the DMCA?

I assume cma is suggesting that the contract would allow Epic to revoke the license of anyone that failed to pay their 5%.

Once Epic exercises that right, any further distribution of the product would be a violation of Epic's copyright and Epic could file a DCMA takedown.

Because the developer doesn't own the copyright to the engine?
