That comment did make a major mistake. Arch Linux is not a source distribution. But the mistake notwithstanding, it was otherwise well-reasoned. Your response was not.
You can mock the point that there is still a benefit in sharing a library a few times, and the article ignored the few libraries that get shared a lot. But said point remains true.
You may think that Android isn't relevant to the article's point. But the tradeoffs between static and dynamic linking are true across operating systems. The challenges that Android has had because of static linking are therefore worth paying attention to. Refusing to look for parallels to inform your intuition from is simply refusal to learn.
