Hope you have money to fight them. I stuck to my guns on a wrongful one like this and while Digitalocean and Cloudflare both had my backs (surprisingly before I even asked, both of them got a lot of good will on that - they informed me they already checked and it was spurious!). Google didn't have my back though and immediately caved when they upgraded their sham copyright infringement claim to money laundering and fraud based on nothing - a fully static website with no backend calls. Good luck! I still have the sites exactly as they were just to spite them and will keep running them at a loss until I'm dead. Copyright infringement my ass. This abuse has got to stop sometime.
