Nobody forces you to buy an iPhone, or any phone for that matter.
The 'security' argument is non-trivial when you consider the private information on most peoples' phone.
Apple's total vertical integration has produced some very capable, and relatively secure devices, and that's why people want them.
CMA, HMG, Uncle Tom Cobley etc. are welcome to build their own phones, just like Amazon and Microsoft did, instead of trying to break other peoples' phones.
My outrage would be reserved for the companies whose WHOLE BUSINESS MODEL is selling spyware to nation states to allow them to steal private information from target individual's phones.
