Yandex steals mobile traffic from webmasters?

You could already read this post on Yandex’s blog, written as always sensibly and defiantly.

Let me quote the most worried about me fragments:

“Today, we present you with expanding descriptions - another way to get an answer without downloading large and inconvenient for the phone sites .
')
... special button. By clicking on it, you will immediately see more information from the site. That is, you are more likely to find the answer without loading the found page . ”

Well well. That is, while Google is sending letters with the text, they say, "Man, soon mobile traffic will be more than usual, here's a special mobile Adsense" site, and the webmaster in this scenario should receive zero conversions, zero banner impressions of his advertiser. Well, or zero hits of the same Adsense or Direct. That is - no matter how you throw, everywhere is zero.
But now the user can find out how many eyes a bee has without spending traffic: this is time and money! What a sweetheart.

It seems to me, or is it already beyond the edge? I would like to look in my eyes to hear the official comment from the search engine number one.
