Lately I've been reading this article about mobile app development. On page 25 / page 28 they talk about centralized and decentralized mobile application portals. Unfortunately, the article is very dated.
Let's say I want to categorize the main mobile platforms nowadays. Initially I would come up with something like this:
How would you complete this? I didn't find a way to validate these information. Google i.e. should be centralized because of the Google Play Store. However, there are alternative ways to download Android Apps like Aptoide. And then there is the Opera Mobile Store. You can download apps there for every platform. What does this mean for the categorization of mobile application portals?
Update: I'm still looking for some answers since I didn't figure out yet how to validate the information above. Any help is appreciated!
Update 2: After doing some further research, I was able to complete the list above. However, I'm still not sure if this really is correct. I added some bounty for those interested in reading the article and helping at my problem. Thanks.
Your list, so far, looks correct to me but Firefox OS has it´s own marketplace. So all of them have a way of working out and install your own stuff out of the store. Maybe Android is the most open of them all in that particular sense but they all try to keep the users hanging from their own named marketplace
