It's hard to know what goes through the minds at Google. It seems they like to get on a mighty large moral high horse. In addition to the crypto ban, they also recently announced a forthcoming ban on bail bonds. Why? "Studies show that for-profit bail bond providers make most of their revenue from communities of color and low-income neighborhoods..." I doubt this ban will have little effect on the bail bondsman business, just as I believe it will have little impact on cryptos and ICOs.

Now there are reports that Facebook has had its own interest in cryptocurrency. https://www.zerohedge.com/news/2018-05-11/real-reason-why-facebook-banned-all-crypto-ads.

So, where does Google's real interest lie? Is an ICO/crypto advertising ban a moral stand or are they protecting their own interests?
