The articles are there, they just maybe aren't widely circulated because Coinbase is so popular, and users generally don't like thinking they are using a scummy exchange, and prefer to turn a blind eye to the whole thing. Just Google/DuckDuckGo Coinbase insider trading or Coinbase Digital Currency Group and you will get plenty of hits confirming what I'm talking about.
Yes, I know that when I will search in Google for #DeleteCoinbase there will be plenty of articles.
I wondered why I haven't seen anything in Google news or other crypto related media services?
I am using Cryptopanic which is always on and with my filters set up so I see all important news and there was nothing to find in the first days.
Today I see already articles popping up on Cryptopanic and other services about Coinbase so it was just a piece of very fresh news, I assume.
