As per the data released by Stat Counter, Yahoo's market share in internet search market is only 1.52%. So I doubt anyone will be interested in such news against bitcoin.
https://gs.statcounter.com/search-engine-market-shareBut I don't really see this article as an attack against the crypto market. Because it is promoting altcoins through this article. So even if this article shows any impact on the crypto market (highly unlikely) it will probably be a net positive.
If Google had released this article, then it would have been grave concern. But who cares about Yahoo anyway!
