> Self-Correction is important, but even fewer people will do it. Defaults Matter. People just don't dive into VSCode and rip out Microsoft's analytics tracking code en mass. It doesn't happen. People use the defaults.
I concur, defaults matter. I am not saying that Ubuntu is a distro for privacy conscious people, however by default macOS and Ubuntu should have similar levels of tracking (however I do believe that Apple OS phone home much more than Ubuntu, AFAIK the actual tracking/telemetry of Ubuntu is minimal while macOS has the standard for a proprietary OS [1]). That is, much better than Android or Windows, however worse than a distro like Debian, for example.
> In the face of these two assertions; Open Source is important in the fight for Privacy, there's no doubt about that. But even more important than that is Trust.
Sorry, there is no way to trust closed source software. I really think it is strange people claiming that Apple are respecting their privacy and when Apple does things that are controversial to privacy (like the time they're got tracking GPS in iOS devices) they just say "hey, Apple does respect my privacy so it is fine".
For another example, Apple must receive everything you type in Spotlight so they can show search suggestions, exactly the same as the Ubuntu case, however in Apple case it is fine for some reason. Go figure.
I think you're right that you shouldn't trust Canonical, however you shouldn't trust Apple either just because they say in public that they love privacy and because of some of the things they divulge to public, because in the end this is all propaganda: while it is really nice that they have things like encryption by default (BTW, encryption does not increase privacy because if Apple wants they could still read every file in your system), you can't trust Apple that they don't do other nefarious things.
Just to conclude, I think Apple is more trustful than say, Google or Microsoft. However I wouldn't put macOS as a more privacy OS than even Ubuntu (since like I said, the amount of telemetry in Ubuntu should be minimal compared to macOS, and we can never know because it is closed source), and Debian and other Linux distros is really above anything macOS can offer in terms of privacy [2].
[1]: I don't know macOS, however I have an iPadOS and by default it enables by all kinds of analytics, and also generates a unique track ID for ads (you can disable both, however this is the default and at least the option to disable track ID for ads is not shown in the Welcome Wizard, maybe the analytics is shown however I don't remember).
BTW, just looking at the information that Apple makes available in iPadOS about "Analytics Data" it has WAY more information than anything that was said in Ubuntu in this thread (if you want to check just go to Settings->Privacy->Analytics Data). I think macOS should have something similar, but maybe someone else can confirm to me.
[2]: Privacy, not security or other things. Security is something questionable, however I do think most recents version of macOS seems more secure than your traditional Linux distro.
