Nothing is really stopping me, I just think iPhones align better with me now.
I am going to give 3 examples of why I switched from Android to iPhone. 1 - I used Samsung Galaxy S every generation till the S5, flashing ROMs every second day and I got tired of it. One thing that particularly bothered me was when I got my officially branded Galaxy S car holder, Car charger and a lot of other accessories and they didn't work with the SII.
2 - I use to jog quite a lot and used the arm strap with the cable and I thought I want a phone that prioritizes wireless audio. Apple was the first company that did that. I would have thought it would have been Sony with some of their previous phones.
3 - Samsung had many of the things I like in iPhone now already back in the Galaxy S and SII time. S Calendar, S notes, S diary, S transfer I think. That was dropped as a novelty after a few times. Once apple start with something they keep it, at least for a while.
I know phones are more mature now and Samsung probably doesn't do this anymore (Or hopefully they don't). But I already made the switch and I don't feel any reason to switch back at the moment.
Why I like iPhone: 1 - It doesn't change much over generations which helps with not having to buy new accessories the whole time.
2 - It doesn't allow me to change much so I don't bother changing much (I still do the dev betas etc, but they are not as time consuming as Roms)
3 - They don't generally try to be first to the market
4 - Privacy is better than commercial Android (I know you can get Android builds that are better)
5 - I like(d) that the App Store is the only way you can get Apps
6 - I like the eco system (I now have homepods, apple tv, macbook, iPad, iPhone, airpods and watch) - I know Samsung has a good one, but too late.
7 - Homekit/Homekey and carplay/carkey - I literally can walk around without keys. (I know this isn't unique, but again when I bought by car Apple was the only option)
8 - I don't feel like I have to upgrade every year.
I think I can do most my likes with Android as well. I just like the way Apple does it currently and they restrict some of my shortcomings.
I am not from the US so might be wrong, but I think it works the same as in mine. It is because they tax income not wealth (which would be difficult I guess). Elon can probably live on $0 income very comfortably by his standard. More than 1% of income earners will be affected at some point as you age up, inheritance etc. Maybe not 30%
