It might sound better but it doesn't align with the fact that not only Apple and Google are new entrants but the field is flooded with more competition then ever before.
Apple blasted open the gates at the carriers and now the writing is on the wall: build a better mousetrap and they will come. Android/linux is a set of cheap building blocks.
I certainly meant it in the most positive way. I'm a big iOS fan but I'm also a big Android fan. To say that Microsoft, Apple and Google are are going to shut out new entrants misses the fact that Android is mostly open sourced and ideal for new entrants like Xioami and Amazon to build on.
