To be fair, you’re right. The features you gain when using multiple Apple devices are actually really good. I didn’t word my post very well… What I meant was that people talk about getting “locked into the ecosystem” and that’s why they can’t leave. And I don’t know what they’re going on about because that’s a lie. Most of the software available is available on platforms, so you can carry them with you as you please.
You're not the only one that doesn't word their posts very well*. I imagine that many people who state that they "can't leave" because they are "locked into the ecosystem" are overstating things a bit. You can always leave. You are never locked in. You always have the option of making a change, it becomes a choice based on how much time, money, effort you want to put into it.
[note: the following is a slightly tangential example, feel free to skip if bored]
Additionally, it isn't just the phone that cause issues. For example, I spent four years migrating my family from Verizon to Cricket (five phones) in order to save money. Cricket is cheaper. I have even purchased a GPS only version of the iWatch because there is no cellular option for Cricket.
Last year, I moved into a strong Verizon area. I would love to switch back to Verizon at this point for quality of access and a more functional watch, but I don't want to get new phones, SIM cards, sign up for two services (some of my family still live in solid Cricket areas). I lie to myself and tell myself that I am locked or trapped, but I am probably just lazy and/or not dissatisfied enough to change.
In sum ecosystems are not lies. We lie to ourselves to avoid the level of effort we believe it would take to do something different.
*It isn't clear in my post, but I count myself as someone who doesn't word things well in posts.
