Apple isn't even the #1 handset manufacturer (they are #3 or #4 depending on who you ask), and far and away isn't the #1 laptop manufacturer.
The attitude that it is a monopoly is exactly the disconnect between this article and your comment. The article thinks your market will just move without different revenue models. That is difficult, it's probably better to find a different market and revenue model.
Your comment is saying that it's worth trying to get Apple to change. That is difficult, near impossible, where they have no incentive to change unless you threaten change yourself with a different market/revenue model.
It seems like your hand is forced - you must do both. You must have a compelling market outside of Apple somehow, and you must petition Apple to change so you can keep access to their market.
I have strong feelings about Apple & Google making "markets" that are not fair/regulated the way I would like - but this idea that it's a monopoly to be "broken up" is not representative of reality.
