What does it mean to "own a computer"?

Do I own my M1 MacBook Air? Did I own my TRS-80 Model 4, an 8-bit, Z80-based computer circa 1983? Well, I didn't lease either one of them, I bought them outright. Apple can't demand their hardware back now any more than Radio Shack could have demanded theirs back then. So that's owning, right? No?

You say I don't own my Mac because I can't put a different operating system on it. It's true, I could run multiple operating systems on the TRS-80. Sort of. There was TRSDOS, CP/M, and... several nearly-interchangeable TRSDOS clones. Of course, I can run a lot more on the M1 if you count virtual machines (including all the TRS-80 operating systems), but I know that's not what you mean. You can run any OS that's been ported to the Mac on the Mac, though, and there's already work being done to port Linux and NetBSD. Do I not own the Mac because Apple's security measures make it difficult to do that porting?

You say I'm dependent on the largesse of Apple and they can "take things away" from me as long as I'm using the Mac. And, it's true they have a potential level of control over what I can run on macOS that Radio Shack didn't have over TRSDOS. Yet for practical purposes I depended on the largess of Radio Shack, too, and when that stopped, the writing was on the wall for that compuer line. Not the same thing? No, not exactly, but I bet you can't name a Mac application that you can't run because Apple pulled a hidden switch that stopped it from running. You can name a few that you could run a decade ago -- or in a very few cases, a year ago -- that you can't now because the OS changed, or the hardware changed. I can't run my once-beloved crazy writing brainstorming app, Dramatica Story Expert. But that's because its developer is legendarily terrible at keeping up with modern Apple hardware. It isn't because I don't own my computer.

You say that things aren't "private" on the Mac. What's that mean? The local data on the Mac is more protected than the local data on the TRS-80 was, I can tell you. Forget encryption, stuff rarely had plain text passwords! Data that isn't local is a question mark now, but it was a question mark then, too -- to the degree it was possible to have non-local data on places like BBSes and Compuserve and even the early Internet. I have way more data "in the cloud" now, but in many ways it's a lot more secure, because we weren't just thinking about security in the same way three or four decades ago. As for ad tracking, I'd argue that's a really important conversation about privacy, but it's not a conversation about "owning my computer" unless we're really stretching the metaphor.

And in the final analysis, "you don't own your own computer" is a metaphor, a semantic sleight of hand. I'm surely playing a semantic game here myself, but my issue with a lot of these arguments is that they're presenting as something that they maybe aren't. They're maybe less about liberté, égalité, fraternité than they are about nostalgia for a (remembered as) simpler, more tinkering-friendly time.

Perhaps we're going to return to a time where it's difficult to put an OS on your computer other than the one sanctioned by its manufacturer. Is that great? No. Does it mean we don't really own our computers? I'm just not sure I buy that.

[To vainly try to head off the "but iOS" responses: I'm explicitly talking about Macs in this example. And no, I don't expect Macs to ever be locked down to the degree iOS is. That's a rant for another time, though.]
