That's how things work now. You think having a copyright on something will matter if the multibillion dollar company fights you and drags out the legal process until you run out of money?
A small creator doesn’t need a lot of money to sue a big corporate entity that infringes their work because (1) the statutory penalties for copyright infringement are intentionally high and (2) lawyers will take cases on a contingent fee basis if there’s a reasonable chance of winning.
