Apple's business model heavily relies on planned obsolescence to bully you into throwing away YOUR working iPhone when they've decided its time for you to drop another 700-1000$ by making their latest OS so slow that your phone is essentially unusable. Of course you'll also have to throw away all the expensive accessories you might own because the connection port has changed format too, yet again.

At least on Android I can install a custom ROM, root it, and install a system wide adblocker like adaway. Oh and also my phones cost under 300$ and I can keep them working until I decide it's time to replace it.

Because android works better for me doesn't mean it has to be the same for everyone, but in any case Apple is out to milk money out of you and not to save you from google. Neither companies have your best interest in mind, you're just there to make them money.
