The market has spoken, hence why apple has received the adoption it has in my opinion. I don’t necessarily think it’s a monopoly because I agree with the response below, people aren’t forced to buy phones and certainly aren’t forced to buy apple phones.
Now with that being said, the market tends to change its tune over extended periods of time. These types of things may just be a blip in the road for apples adoption or could have a longer lasting impact on people’s willingness to give apple the power they have. Time will tell
