This is 100% on Radix, not on Google. Google and Microsoft can (and probably should) have a registry of known-abusive websites. False positives are inevitable, so these should be taken with a grain of salt, but in most cases they're correct. Their lists are a lot more reliable than those from the "traditional" antivirus/anti-scam vendors that will list anything remotely strange to pump up their numbers.
The external people treating these lists as absolute truths and automatically taking domains down are the ones at fault here. Google didn't grab power, Radix gave it to them without asking.
