I think you'll find that most, if not all, human conversations are embedded in a context, which carries assumptions, so that participants can understand each other without iterating all of their definitions. That's why, for example, I don't have to start every conversation in my life by clarifying that I will not be explaining everything in terms of Xenu and thetans.
And if I did want to explain things in those terms, I should first explain why that's a valuable frame to adopt.
No, macports is non-native as well and is an excellent, stable alternative, although Homebrew has slightly better coverage. Homebrew's main issue is that it was written from scratch, ignoring lessons from 30+ years of package management experience, and there's no obvious benefit that doing so has brought. Compared to macports, which is based on freebsd ports, Homebrew is brittle and normal operations frequently result in an inconsistent state.
In my experience, unless your needs are extremely basic, sooner or later you'll run into an issue where the solution is basically to commit nuclear warfare on your filesystem and start over again. Also, expect to rely on random blog posts and stack overflow as the de facto user's guide (which maybe is just the state of the world for everything now.)
I'm constantly amazed at the number of upvoted, top-level comments on HN (on any topic) where the underlying premise is first, thousands of people with actual skin in this game are wrong, whereas I, a drive-by commentator, posess True Understanding. I'm not suggesting that a large number of personally invested people is proof of correctness -- but certainly it reeks of arrogance if your argument assumes without proof that an uninterested commentator is better informed than all of them. More so if your only comment, given such a grand assumption, is to reiterate basic economics.
At least you could try to explain how you think it is that so many are mistaken about something so elementary that it fits in two short paragraphs.
