Re: Just another attempt
Apple is simply not allowing that Russian chat app on their App Store. There is nothing stopping the authors from offering it on the Google Play Store for Android.
Apple doesn't have a dominant share in app stores, and no country has laws against a company being able to restrict what it offers in their own store. If I want to sell my widget on Amazon, and contact them but they say "no thank you, we already have widgets and don't need another" I can't go whining to the FTC or EU competition authority because Amazon doesn't have a dominant share in online stores - let alone stores in general when you include both online and brick-and-mortar. Though I'm sure that's their ultimate goal - if they ever achieve it then they will experience problems like those Google is enduring.
