(Of course this anecdotal) I see no correlation which source code control software. What I think is key for open source is the quality of internet access we have these days. You can copy any repo without really thinking about it. The other aspect is that open source is extremely mainstream. Mobile is still a reflection of the old world where everybody tries to make a small amount of money which some closed source apps. Lots of people realize that is it is better to collaborate with other people in an open source project then to be on your own writing your own programs. All of that would work just as well on SVN.
