DMCA is such a shitty law. But companies like Google choose the safe route and believe every DMCA claim without first using humans to investigate them (because that will cost more money), and this is the result.

I pity the independent creators and makers who get fake DMCA takedowns all the time while Google does nothing to protect them.

If Google really wants to save themselves from this kind of trouble, maybe spend some lobbying money to get DMCA repealed.
