I see comments like yours, and I seriously can't tell if you're trolling or whether you genuinely believe this. However, I'll try to answer (once) in good faith.
There are so many things in life, due to either scarcity, lack of options, laws, or prior investments that we have made, that we can't leave them easily, even when we dislike a subset of our choice.
If you hate Comcast's service, but they are the only available broadband option in your city, would you leave your city just for better internet?
If you don't like 10% of the policies of your current government, but dislike 50% of the policies of the opposition, would you start your own political party?
I like a lot of things about iOS as a user, including the quality of their hardware, but I dislike the dictatorial control that Apple exerts over both developers and consumers. Not just their anti-steering provisions (which is pure rent seeking), and lack of sideloading (which I want), there's no way for me to write my own app and install it on my own device, and have it run permanently without paying Apple even more money.
I bought the phone at full price, I hate Apple's attitude that I have just bought the privilege of using it as per however they see fit. And so, similar to above, my alternative is to switch to something like f-droid, and lose my hardware, lose my purchases, and in many cases, lose my ability to even use my phone for standard communication (eg: iMessage). Or maybe you would suggest that I build my own phone company
In all these cases, the alternative option is possible, yes, but it's very impractical and infeasible for the vast majority of people to pursue, and they come with serious negative costs. So we pursue them only when things become unbearably bad, as a last resort.
And so the feasible option is to complain, protest, and try to leverage the government/courts to change the rules so that large companies can't take advantage of us and keep exploiting us in a "boil the frog" manner. And if that doesn't work, then one day, my cup of frustration will overflow, and I will switch over to f-droid or something
