gatekeeper

　グーグルのサービスを提供しているアルファベット社は，ＥＵから3000億円の罰金を支払うよう命じられました。インターネットでのショッピングサービスで独占禁止法違反をしたことが制裁の原因です。
　記事の中で気になった表現は"gatekeeper"です。『Wisdom英和辞典第三版』(三省堂)を調べると「門番, 門衛, (企業の) 仕入れ品[先]管理者, (企業の)情報管理係」などという意味がありました。ＥＵではこの調査に7年の歳月をかけておりました。(Ume)

Google hit with record EU fine over Shopping service

The probe was spurred on by complaints from Microsoft, among others.
The rival tech giant has opted not to comment on the ruling, after the two struck a deal last year to try to avoid such legal battles in the future.
However, one of the other original complainants - the British price comparison service Foundem - welcomed the announcement.
"Although the record-breaking 2.42bn euro fine is likely to dominate the headlines, the prohibition of Google's immensely harmful search manipulation practices is far more important," said its chief executive Shivaun Raff.
"For well over a decade, Google's search engine has played a decisive role in determining what most of us read, use and purchase online. Left unchecked, there are few limits to this gatekeeper power."
