TL: DR he doesn't want to switch because he has other Apple things.
I try to avoid being too negative about article like this, but I can't help but question why it was felt this article was necessary. Ecosystem lock-in is the biggest and most well-known reason people don't switch platforms. After people dealing with this for nearly 10 years with smartphones since the first iPhone and first Android, it's not really news.
This is one of many reasons to diversify your investments, e.g. where you invest your tech.
I used to be tied to Apple between Macbook Pro/iPhone/AppleTV/iTunes for all my devices, but once they switched to the lightning connector and started pushing OS updates that rendered my otherwise perfectly functional hardware useless, I decided it was time to divest myself of dependence on a single provider for tech.
Spotify replaced my carefully curated library of music, and its as good or better. As easy or easier. Its multi-platform and everywhere. Online or offline.
Cloud storage? Dropbox for the essentials, and BTSync for the big stuff.
Gmail is hard to beat, and I can import/export my contacts from there, but I dont need google for more than that, and I could tolerably go elsewhere with carddav support.
Outlook/GCal remain calendar giants, but I dont depend on that as much so I can cut ties when necessary.
I opted for a Nexus 5 for my last Mobile purchase, and have the option of Ubuntu Mobile, FirefoxOS, and need to investigate a CM build as well.
There are plenty of benefits from floating atop the dependence, and its not that hard to do so.
In the end, being a dynamic consumer makes providers work towards more compelling products, instead of just drafting off of zealots for a few years at a time.
