Hang on, developers are the ones complaining about one of the two options available.You can’t force there to be more competitors in the market than the market will support. We used to have several and the market decided only two could be supported. This isn’t all that different than the desktop market, Windows and macOS. Yeah there’s Linux, but it’s quite niche. It makes sense why markets don’t support a wide range of OS’s. Popular developers aren’t going to spend the time putting their apps on six different OS’s. They’re probably going to pick the one or two most popular. A lack of important apps then kills off the less popular OS’s. At this point, all governments are left to do is regulate the ones that survive since new competition isn’t going to be coming in to disrupt the market. Windows and Mac have been the only two significant desktop platforms for decades and that’s almost certainly going to tone the case in smartphones with iOS and Android as well.
Surely developers are desperate to make their apps available on any/all competing operating systems that emerge so that these operating systems have to compete for the developers talents?
