> DuckDuckgo is a minor player, but microsoft's Bing isn't.
DuckduckGo, Qwant, and Bing are all the same player.
DDG and Qwant just pull Bing results.
Bing is the only real competitor to Google.
>or search.
Erm. I think it's absolutely there on search. The existence of competitors doesn't negate monopoly status.
And the accusation can be legitimately claimed, that they use their monopoly status in one market (search) as leverage to give other services in different markets a leg up over the competition.
MS can't leverage Bing for the same - no matter how integrated Bing might be into other products.
If Google tells people to use AMP or be de-ranked, that's monopoly power. Flat out.
