Lawsuits are cost of doing business in the U.S. They don't need to increase potential surface and invite them though. Knowing that there is potentially copyright material does not give you standing to sue them, unless you can show reasonable cause that they could have used your copyrighted content no court will take it to discovery to prove it conclusively, your case will be thrown out for lack of standing. However if they share their data set, then you can show that they actually took it and have standing to sue them. Making any potential case more complex and expensive.
