The second time this year, Apple is being investigated by Japan's Fair Trade Commission. This time there is a possibility to shrink the web platform dedicated to the web that compete with the App Store for Yahoo.
It seems that Apple Japan is playing intense. This summer, the FTC has caused Japanese telecommunications operators to stop making iOS terminals pay subsidies.
With Yahoo's Game Plus service, users were able to play games online without requiring application downloads. It was released last summer and 52 companies participated. It was doing fine, but Yahoo was thinking about extending it to productivity software.
Apple Japan, threatening Yahoo
Later last fall, Yahoo greatly reduced the budget of Game Plus and basically ceased advertising the service. Yahoo informed the business partner that it was forced by Apple Nikkei Asia Review.
Yahoo obviously depends too much on the income from the App Store to take Apple's anger. I do not know how much revenue is in danger, In the US version of the iOS store, 14 applications of Yahoo, such as Tumblr, Flickr, (of course) Yahoo Mail, etc., are posted.
In consideration of this, Japan's Fair Trade Commission is considering the possibility of anti-monopoly law violation. However, Yahoo does not seem to be cooperating with the survey. It is still feared to lose money from the App Store in cooperation with the authorities.
