No they not do Press Release (pay to get article promoted) anymore becoz alot of ICO wanted to use it and they shut it down.
Just had a look at Coindesk's terms, and it seems that you are right. I can't exactly recall when it was, but I remember fairly recently having read an article clearly stating: sponsored article. It was related to gambling.
I don't think it's just related to ICOs, but more the overall sentiment of the general market towards paid articles and their nasty bias. They partly have been blamed for the shitload of fud that we had to swallow recently.
If they actually don't accept any form of paid incentive to publish articles or reviews, then we'll hopefully see the market become less subject to all the negativity. I get it that they need to earn money, but there are limits.
They probably realize that now, or at least, I hope they do.
