I don't think any official news has been published regarding this one. Anyway did you read the article completely? The article itself gives us proof that the crypto ads have not been banned yet and neither they are thinking to do so. Just check the snapshot from the article writer and you will see the mail conversation with google says that they have not banned any ads and there is issue with platform for displaying the ads at all.
Also, crypto currency is big market for the platform like Google because Crypto currency projects invest heavily on the ads and thus google benefit a lot from that.
True, if this news is going to go all out in the internet it will surely give the crypto world a big disadvantage. Yet i will not believe easily an article which has negative feedback on cryptocurrency because this would be another FUD to bring down crypto.
