Oh, the bad news is, they would only allow regulated/verified exchanges to use their add platform. Meaning - You want to advertise your crypto platform through google? Get your shit verified. I'm sure twitter, facebook, medium soon will follow the same. In the conclusion, fuck decentralisation and let the government regulate everything related to crypto.
I say that's a good news. Tired of seeing those ICO ads on my browser and even social media feeds. With that rule at least ICO won't be allowed on Google ads. Can't blame them though because ICO's negative effect for the public is as bad as its effect for crypto. If you want to be fully free of regulation then don't use Google, heck don't use the current internet system. Use tor or something like what Namecoin is doing.
