You can keep your Android phone with that modified version of Android that your carrier or manufacturer has decided to put on it, and get security updates weeks late, or never (if you have a Nexus you’re better off, but who knows if Google is going to keep making Nexus phones in the future).
Or you can root your phone and install the excellent and more swiftly updated Android-based operating system CyanogenMod on it. This is a good alternative, but it’s not trivial to install CyanogenMod, and updates for certain phones depend on volunteers, so, again, you might not get them as soon as you’d wish.
Or, lastly, you can give up, switch to Apple and buy an iPhone.
Keep in mind, this is a piece from a certified Apple hater who manages to shoehorn references to the walled garden, “fanboys,” and Apple-as-cult imagery into a single paragraph. Of this same article. Where he’s saying he’ll probably just give up and switch “to the dark side.”
