You have chosen one property of the iPhone and elevated it to the primary reason why people buy that device, which is entirely disingenuous as clearly people are forced to make tradeoffs in their purchases and nearly 100% of people might despise having locked down devices and yet still buy an iPhone if other things are more important to them... and there are definitely a ton of things the iPhone gets right--both in its hardware and its software--despite* this one glaring thing it gets wrong.
Almost everyone I know owns an iPhone... and yet, almost all of them wanted a more open device and bought an iPhone anyway because it has a longer serviceable lifetime (due to software updates for a longer period of time), has a pervasive brick and mortar storefront that sells accessories, lets them use AirPods, has one of the best cameras on a mobile phone (and here it is maybe-interesting to note that Samsung devices are also pretty damned well locked down: you sideload a browser, sure, but you can't get filesystem access or modify any of its stock behaviors)... I could keep going, as Apple is actually an extremely competent company that has built a great product!
And yet, those people, when given the chance, were all very excited to jailbreak their phones to get more features. The people who are not technical has their technical friends do it for them. The people who did not have technical friends who wanted to deal with that much effort bring their phones to the little shops which do it for you. At its peak, despite being pretty hard to do, difficult to maintain, and complicated to take advantage of, we had more than 10% of people with an iPhone jailbreaking! That is an insane number of people to just write off :/.
