iOS is a better operating system than android. The Apple ecosystem of devices is better than anyone else’s. It also means you can completely get rid of google out of your life. No more supporting their anti-competitive business practices. So a switch to Apple is both an ethical and practical upgrade.
You're casting your opinions as facts, and your preferences as those that are shared by everyone else.
Completely agree that Apple has a better array of devices as anyone interested in tablets or wearables, are better off with Apple in my opinion. However, not everybody feels the need to remove Google from their life - especially considering that Google has over 90% share of search, Chrome on Desktop (so excludes any argument about it being pre-installed) has nearly 70% market share. That would suggest to me that the majority do not share your concerns about Google's business practices. This is even before you take into consideration that I have Google wide controls over all my data within three clicks on Android (Google App, more, your data in search) - not only can I delete the data, I can control what's collected across Web & App Activity, voice and audio, app info and contact info.
Also ethical business practices don't really exist in large corporations, Apple included. They like to try and be perceived as ethical but when your products are made at Foxconn factories with terrible working conditions and high suicide rates, you can't exactly sing from the rooftops about being ethical. What about e-waste? Apple create more than their fair share by making repairs difficult so they can sell you a complete new main board by soldering components to the PCB, components that are usually installed via a socket and in some instances, have been installed via socket in previous generations of Apple products. The crazy thing about this is, sockets would actually cost Apple less to offer different specifications of Macs, but this isn't an issue as the profit from repairs exceeds not saving cost in the first place. However, this means an entire main board is going to waste when only one component is damaged.
Louis Rossmann has some good videos on YouTube about how Mac users have been quoted more than the cost of their entire machine for repairs, but he has ended up fixing the issue by replacing a couple of capacitors. One interesting video is where he testified for a repair company in Norway (I think), who were sent a cease and desist by Apple because they were sending GENUINE Apple screens to China to have the cracked glass/digitizer replaced before sending them back. Apple were claiming this meant the parts coming back were counterfeit....
Unless you're using a Fairphone 3, you can't be using ethics as a reason for your phone choice.
