I don't own an iPhone, but I assume you have the same trouble I do with spam texts/calls and no real decent blacklisting solution (most apps just don't work and I'm not going to throw money after money to find the one that does work in that pile of shovelware they call the play store.
The author complains about Apple technical support, but brings up a anecdote about a laptop (I thought this was about a phone). Can you bring a Samsung phone to a Samsung store to get it repaired? I remember needing to mail my Samsung phone in for warranty repair and the screen coming back with a diagonal slice where they cut the packaging open. That sucked, but I am not going to blame all of Samsung for that (it was probably an unfortunate mistake) or blame the Android ecosystem.
