As someone that used to hate Apple and still does, I use apple products (don't buy them myself). There are many reasons people use Apple products. From the support to the high quality of their products. There's also the fact that a macbook can run all 3 main operating systems at the same time, whereas no other hardware can easily and legally do so. Macbooks are also pretty much the lightest and smallest laptops you can get.

Some people also get them because of loyalty to Apple from the past, or because OSX is unix-compatible.

The point I'm trying to make is, you can disagree with Apple and still use their products. I hate Apple but my work provided me with a mac mini and a macbook, which I use every work day. I also have developed iOS apps even though I've never owned an iPhone.

Also, if you are talking about iPhones, you are going to see a lot of those everywhere because you really only have 2 viable choices anyway.
