I agree with the sentiment, but I approach it a bit differently. I treat my mobile device more like an appliance. For me, it's primarily a phone, an email client, and a web browser. I don’t rely on it for much beyond that—though I do run RemoteVNC on it occasionally.
This raises a deeper question: what does it actually mean to “own” something?
Take my analog watch, for example. I own it, but my expectations are simple—I just want it to keep time. If I wanted a mobile device that lets me install and run anything I want, I’d opt for a Linux-based device with a cellular modem. That kind of ownership comes with more freedom, but also more responsibility.
I’m not saying people are wrong to demand side-loading or open platforms. Manufacturers respond to market demand, and if enough people wanted fully open devices, we'd see more of them. But the reality is, most consumers prioritize convenience and ecosystem integration. If total openness were a top priority, Apple wouldn’t be as dominant as it is.
